I recently got into lab scopes and am currently buying a picoscope. I was recommended your videos and I'm finding your content EXTREMELY beneficial. I probably consume 4 to 5 hours of your videos everyday after work. Keep up the good work brother. 🙏
Awesome! Thank you. Be sure to watch my picoscopes basics parts 1 and 2 videos too my new friend.
Jakawild welcome to the club! I used to do what you are doing and watch Scannerdanner for hours after work 😎 it changed my whole career and made me the top diag tech at pretty much every shop I've ever worked. Lab scope diag is literally life changing lol
@@jeffreywilsonrubikscubeonb2428 thank you so much for this comment ❤
Thank you! I'm currently the only one attempting to use a scope for diagnostics, I work for a Ford dealer. I'm kicking myself for missing out on lab scopes all these years.
Nice! 👍🏻 You’ll save yourself a ton of time on diagnostics with a scope and also give yourself way more capability. I try to show the guys all of the time what they’re missing and their response is always something like “I don’t know how to work that thing”. I keep trying to explain to them that it’s nothing more than a glorified super fast graphing meter showing voltage over time but they refuse to hear it. A scope was a necessary tool years ago and it will be even more so going forward as technology progresses in this field.
Global disabled and being frozen needs a drive cycle. You need to accelerate to 80km/h and then coast to 50km/h without braking. This needs to be done 5 times. There's also other criteria like temperature and fuel level that needs to be confirmed. Service information all data and identifx have the criteria. Awesome video
Also you gotta step on the accelerator pedal in a CPR manner, jerk the steering wheel exactly 30 degrees left and right, while maintaining a six o clock flux capacitor spark b u t t plug but no bud position, while pulling and turning the key in the ignition, then press and hold and wait for the system to reset and trigger the alarm. And I thought the BMWs were over engineered. Dear Chrysler!
These companies oughta go back to hiring real engineers with real world common sense like Scanner Danner.
New costumer complaint! Spider infestation....
Was that Autolite the right plug for the Durango or did someone make a mistake and put the wrong number plug in it?
I do not know for sure.

What a neanderthal.
Just having the wrong reach (short) plug can lead to idle misfires, even with a plug that’s not defective. The location of the spark within the chamber is important. I used to do engine development for Chrysler, and ran lots of idle stability tests with different plugs on 4V heads. Reach and electrode length can have a big impact on 4V heads. A lot of 4V heads use medium or long electrodes for this reason. Pentastar was the last program I worked on (although as a Program Manager).
Did you explore spark plug indexing on the 4V heads?
Very true. The spark location within the incoming air fuel mix, can absolutely effect the ability of the A/F mix to properly detonate. Diagnose Dan actually did a video on this exact scenario.
Really cool to hear your input..
@@rickw.9298 I personally did not investigate indexing, although the guys that developed the 2.7l V6 did, and I read their report. There is an effect, but it was minimal, and not worth the effort on production engines. I did investigate different plug types, and multi-strike ignition systems, and found that single J-strap plugs had better combustion stability than the multiple ground electrode types (and by a significant amount). I theorize that the multi-strap plugs simply have greater potential to quench the flame kernel. Multi-strike systems were good for extending the lean misfire limit and EGR misfire limit.
yes i agree and o.e. is the way... Champion work fine !
Apparently you will need to coast down from high speeds at least five times for the Adaptive Numerator to gather enough data to complete the relearn process.
I'm sorry my friends, I forgot I have a wedding to go to today, so I can't stay to watch with you guys.
Just want to say thank you for all of the good information about the known mechanical issues with this engine, and then also remind all of you that when you see this type of secondary ignition misfire on a labscope, that this is NOT a mechanical or fuel system fault that would do this. Sure you can get turbulence and things like that, but go back and look at the pico images in part 1 and then the images from the Verus in this part, when the plug was moved to the number 5. These are always secondary ignition faults when you see this (not fuel or mechanical issues) . Burn them in your mind 😉
Love you guys! I learn from you too. Have a blessed day.
EDIT: one more thing! This is the second time I've seen a misfire counter, continue to count, after a fix (no more misfiring taking place) on a Chrysler/Jeep product. Be sure to clear all adaptives and if it is available to do a cam crank relearn, then clear codes, after fixing misfires on these systems!
James' beard just keep getting longer, Paul's biceps just keep getting bigger, and Caleb's camera work just keeps getting better - I love you guys!

Excellent video! I've had the same problem at my shop the past year or so with inferior parts, especially with coils and sensors. I have Mevotec supreme lifetime ball joints come back after 5,000 miles on a lifetime warranty part. Moog is not much better after manufacturing switched to China. We are staying OEM now, not worth doing the job twice. Great seeing all the Danners together at Jimmy's shop!
Too often I find Autolite plugs in Hondas and Toyotas. People go to the parts stores and the counter guy says "Do you want the $8 Autolite plug or the $17 NGK plug?" Customer says, "Are they the same?" Counter guy says, "Yeah, they're both Irridium." That's how this kind of thing gets started. Even many techs don't understand this rule: Spark plugs and O2's....ALWAYS go with OE. ALWAYS.
Horrible isn't it?
Majority of things should be OEM when possible. Especially electronics like sensors and actuators. Cost more but are usually always more reliable and accurate
Or use an oem brand ie like denso on honda or toyota, I used them in my dodge without fail.
@@carmo9693 While NGK and Denso are great plugs I don't usually put them in a Chevy or a Ford. The point is to ALWAYS use the same plug the factory used unless there is a compelling reason to use something different. My exception to this is on older vehicles that had copper or platinum plugs I will often upgrade to Iridium. You can upgrade but never downgrade a plug. Don't put in a copper or platinum plug where Iridium came from the factory, etc.
That said, recently I did put NGK Rutheniums in my 2002 GMC 5.3L as an experiment and, so far, they are working well.
From the internets - “As for the misfire monitor. That's not a Chrysler thing, a lot of those parameters are set by Industry standards. The PCM detects misfires by monitoring the crank sensor. As a cylinder fires the crank rotation speeds up. The PCM knows where #1 cylinder is on the crank tone wheel, so from there it knows which cylinder should fire next. If it doesn't see that acceleration that means a misfire has occurred. It's quite complicated, it needs to be able to adjust its readings over time in order to factor in engine wear.
If the misfire monitor is set to global disable its because one of the self tests either hasn't run or its failed. It needs to relearn the crank sensor before misfire monitor becomes active. “
Hate dealing with bad brand new parts.. Easy to diagnose but frustrating to deal with..
When i or someone else has reset the adaptives the vehicle has to driven and several acceleration and decels must be done for the ecm to relearn cam and crank to monitor the misfire
Always always always use OE parts whenever you can. I learned that the hard way. More expensive? You betcha. Will you be in there redoing the job in a few weeks or months if you don't use OE? There's a good probability you will be. What's your time worth to you?
Agree but even OE can be an issue. Just did an ABS module on a 2018 Duramax, factory replacement, and the pins were too short where it bolted up to the pump motor! Caused a pump motor circuit code we didn't have before replacing. SMH this was an OE part! I was so mad.
@@ScannerDanner Hi Paul. Was OEM ,or OEM rebuild?It's a small difference. Because,some parts, even OEM, are rebuild, and when you buy something from the dealer, you have to give back the old one,so they can rebuild it, and re sell it to the next victim, em sorry, I mean,next customer😂🤣😂🤣.
@@Lambros_Stefaneas not sure, but it was the only one they had it stock
Given the difference in plug length on this one, i suspect that is this problem (spark in a poor air/fuel mixture part of the engine), but it could be a carbon track.
I had a spark plug with a carbon track following the ceramic from the center electrode to the metal inside of the threaded part. Had to hold it up in bright direct sunlight to see the shiny track.
I Also had 2 different early 90's chevy rotors that arced through the center plastic of the rotor to the distributor shaft.... I suspect a small air bubble in the plastic.
This may not apply to the data issue you were having here BUT, I’ve been told by two different snap on tech guys that snap on buys it’s data by the line, the pids they didn’t buy has inactive or inaccurate data showing. I was told this while dealing with similar issues with snap on data. I would be curious to see what Autel would show on this vehicle. Chrysler is getting to be a pain with data in the aftermarket and especially with snap on scanners
Using another scanner would have been my first move, just to see what happens. Unfortunately for me I only have one Snap On Modis and a cheapo Actron, so scanner weirdness can be very challenging sometimes. I really need to get into the Autel world since my Modis is now obsolete.
@@athhudwhy is your modis obsolete. I see many techs using modis
Drive vehicle, complete 4 deceleration from 65 MPH down to 40 MPH without touching the brake pedal.
For real? That is the method for these misfire monitors to come back online? Fat chance of that happening where we are located lol
@@ScannerDanner 4 post lift method?
You could move the plug and coil to two different cylinders but maybe no easy access, very easy to head of in the wrong direction when you fix it you want to kick yourself thanks for showing wrong moves it’s always easy to be wise afterwards. As long as good moves outnumber the bad ones 👍🏻👍🏻 history of what’s been done can help sometimes can handicap you other times. Some of my repairs have been just shit house luck the end result is what counts a fix is a fix all fixes are temporary anything we work on is a ticking time bomb our repairs are just letting the customer buy a little more time !
Works great on jackstands
Dont skimp on ignition and fuel parts. Youll regret it
El mismo problema tuve en una ford escape 2007. La falla bobinas de encendido
I had a similar issue with this jeep (hemi). It came in with misfire cylinder 5 and the cam was wiped out. The roller on the lifter was seized, this is my 3rd one in a month. I did the cam and it still said misfire on 5 with no misfire. I thought because the battery was disconnected it wouldn't need a reset but it did. 2 weeks and jeep runs great. I was wondering if the hemis have a oil issue to the lifter on 5 because its always 5 and the cam is wiped out. I'm not joking I've done 3 this month. All hemis all misfire 5 and the cams wiped out.
Yes the 6.4 hemi’s eat camshafts. I can’t remember exactly, but I think it was the 2012-2014 SRT’s were notorious for this. I don’t really follow the non-SRT stuff, but I would imagine it was a problem with all of the hemi’s of that vintage. I THINK they did something to solve the problem in the later models, but I don’t remember specifically what the problem was or what they did to fix it. All I know is I wouldn’t trade my ‘08 Jeep with the 6.1L at 200k miles for anything that has a 6.4L in it. They are ticking time bombs from what I’ve seen.
I’m pretty sure the misfire drive cycle needs to be completed before the global disable re enables. Interesting video, hand on forehead to autolite plug lol 😂
But the fans demand videos from The Danner Boys! Good lesson Paul, Danner and Caleb!!
Thank a lot for another great Saturday with your videos.
I watch ScannerDanner videos everyday in the mornings with my cup of coffee before work, Paul you are a great teacher. I have learned so much it's hard to calculate its worth. I also like Pinehollow with Ivan. Technique and approach to diagnostics is half that battle so these videos are awesome.
Your not alone.😁
New parts and engines are the 🦫🐿 walnut 🔩 🐒🪵 $hit nowaday$ and not in a good way. It’s def a cracked b u t t plug. All cylinder heads these days resemble oysters 🦪. We oughta go back to steam engines and real engineering tolerances. And working turn knobs.
4:44 8:34 I learned something today that I didn't know before. 1) All engines with more than 4 cylinders have companion cylinders -- not just distributorless ignition system engines, 2) False misfire counters can register on companion cylinders too -- not just on the cylinder that is adjacent in the firing order.
My understanding is 2018 and above you must register your scan tool with the cloud to view Chrysler data for security purposes. -Reset pcm under Guided diagnostics in witech or battery disconnect and touch terminals. You won’t find info for global disable for this product but you will find misfire monitor disable.
Autolite plugs DO NOT operate correctly in Chrysler Dodge Jeep Ram products. Why the auto parts stores push them I will never understand.
I like that you preached comparing cylinders. My favorite analogy for that was what one of my teachers always called "Sesame Street logic". See which one of these things is not like the others.
I think I know that guy 😀
Thanks Shaun
Put crap parts in and cause you time to fix it.
Charge them twice for your trouble
My wife's car, a 2012 Grand Caravan is having the same issue. The shop said they switched the plug and coil to another cylinder, and still got the same response. At this moment, they said they had lost compression on cycl 2. So they are going to remove the head and check for head gasket, or cracks. I don't think the head gasket is a problem. The crankcase oil is clean, no evidence. of water in the oil, and never have to add water/ antifreeze. Never have to add oil and exhaust is clean. I know this is not a expert way of figuring what's wrong, it is just my gut feeling.
This issue was in the mechanics bulletin. This way the dealers will know about it without having a recall. I hope that we will get decent news later today.
At one time, when I was a kid, I was into building engines, setting up carbs on other kids cars. But as time went on, I got into refrigeration and did not keep up with the engines these days. I am sure if I devote time to re-learning, which I am going to do, I will eventuality I will do well with it. Of course, I am not going to buy all of the scanners, ( like a Pico ) or hat ever just to work o my car. Fortunately, A friend of mine has a great shop and he lets me hang around and learn. Car are far more involved these days. Give me 1970 Chevy 396 cu in 375 hp and I will rebuild it for you and make it "crank ". I miss the old days, being at Motion Performance, riding in the second V8 Vega, or the Motion Camaros , Novas, and Chevelles.
Joel Rosen built himself an empire back then. He was a real good guy. I miss him
seems like if we didn't have crappy parts, we'd have no parts at all :(
NEW means Never Ever Worked in my books, thats why they give warrantys cause things do go bad out the box. But having a misfire idle only issue with a 14 jeep 3.6 right now, it had low compression on driver side and a head was put on by a crack head though. So I pulled the head(it came from junk yard) he had it shaved and compression has come up and misfire isn't as noticeable. The scanner I have shows a misfire counter but isn't picking anything up. It's very frustrating for sure, plugs are champion and look to be newer.
stupid drive cycle cruft. I've had to burn 2 whole tanks of gas before, just to get all the drive cycles complete. ( danged jHeep's)
I would just replace all 6 plugs and coils on this vehicle to the manufacturer recommend ones. This is one of the things that can drive you insane and for what, a few frickin extra bucks.
. your scanner gets the info from global obd data and it froze due to software issues on your scanner, if you had rebooted the scanner it would have worked. Thank you Snapon
No, this was a relearn procedure that needed to be done in this case. Some deceleration events is to going consensus
You may have figured it out by now but global disable will come on tell all the things you reset relearn also it will come on if it’s below a certain fuel level to keep it from monitoring misfires during that period
That's cause you get what you pay for so people need to stop going to the cheapest stuff and at least buy the middle ground parts if not the high end parts. Don't understand people who use the cheapest stuff on there biggest investments like there cars ,houses and such. You wouldn't tell the dentist to put cheap work in your kids mouth to save an dollar lol
Perfect diagnostic Paul. You have a good brother and Sun. Thanks for your Videos and all good for you and your Family.
How nice to film your father and his brother horsing around! 😀
I have had a few Chryslers that misfired from the incorrect spark plugs. One even set O2 codes that had me chasing my tail for a couple hours since it kept testing good. New plugs fixed them.
Also have seen misfire and throttle body codes from weak batteries, going into limp mode, even though it started the engine thanks to a gear reduction starter, it dropped below 10 volts, started and set codes, but only after sitting over night.
Bad parts is also becoming a bigger problem with each passing day.
Our world, lol.
Low quality parts out of China and the parts are in shorter supply. If we understand the Chinese culture we understand that the people there have little or no pride in their work. It's the culture. American culture at least at one point in time was a culture that took pride in it's work, many still do today like the Danner brothers for example. Seems like a good opportunity for starting up manufacturing of quality parts in the US again.. They'll cost more, but should reflect a savings in the long run on labor and life of the parts.
Not really, it has cheap parts that are make in the USA that is also bad, it's all about price,you can't expect to pay ,50 cents for a spark plugs and expect it to work like a denso, also it could of been the fault of the shop buying cold plugs and not hot
Nice catch Paul, the height difference of the plug. Nothing like keeping it simple……
Speaking of bad new parts,I just had a new ,OEM.Nissan fuel pump installed in my 2015 Altima.It lasted 1 day and the car stalled again and had an engine check light come on.I took it back to my mech,he scanned it and came back with a fuel temp sensor And fuel level sensor.He sent it back to Nissan and got another fuel pump.So far so good.My mech said the same thing about never having seen so many bad new parts.
It is so frustrating and makes us second guess ourselves so much
How much time did you waste by ignoring your experience with secondary ignition misfires?
Lol a lot on this one! But the lack of having the ability to recreate this under snap throttle and load conditions had me looking in other directions. I have to say that this is probably the first bad plug that I've seen, that was an idle only misfire.
I learn something from you guys no matter what video I watch , don't know how to thank you enough , all of this is apparently an unending "learning curve" even for experts like you guys , thank you so much for sharing your unbelievable skills .
Unending learning curve indeed! Well put. Thanks so much!
Sorry to comment so late but WOW .! You rec a champion over a Autolite??? Not that auto lite is good , but champion ? Really ? Current techs bony put those in lawn mowers.
Not disputing a hero (in my mind) but champion ?
Champion is the factory spark plug for Chryslers so I recommend Factory spark plugs! Always!
Did you disconnect the scan tool the dlc? I've had to do that to get data back numerous times
That is usually when data is frozen completely and this was only this one mode. But good thought
@@ScannerDanner all I knew to do was to start over fresh. That way I could remove snappy fault from the equation

love to watch if ONLY to confirm that even the EXPERTS (YOU) get frustrated too! Could the lesson be that all monitors must run to completion? Golly, do customers know about completing LENGTHY drive cycles? Seems like you need to hire someone just to complete drive cycles?? YIKES!!!!
Will unplugging the battery work to reset my Fords computers?
Sometimes yes, sometimes no, depends on the system and what it is you're actually trying to reset
Parts Are Crap lately. I put plugs in a 2017 Ram hemi last week . 100,000 mi service. 16 plugs oe was ngk. Not cheap. You can’t even go with Champion in Chrysler . But autolite is NOT oe in anything
There using the Nova as a table. ug
Ran into a cylinder 2 misfire on a 2015 Dodge Durango limited with a 3.6. Cylinder 2 ended up having low compression @ 65psi . Scoped the cylinder and the Piston was rusty looking so pressure tested coolant system to see the coolant leak in #2 from the head gasket with the scope.
Has to go through a long decel to reset.
I've seen a few times on 4cyl Caliber / Patriot false misfire on 2 cylinder simultaneously. Leading to fuel injectors cut and then going into real dead misfires.
The shop would change every damn part without fixing anything.
I get called in. First thing.. clear memory. Then I'm done in 2min. Fixed.
Notorious on 4cyl dodge engine.
Everytime you replace a part on those, you should always clear memory.
Paul. I’ve searched. Page 10 of your book. Watched your video. Why is my iac current high 2004 Durango 4.7 ? It’s like 4000mah. I posted in forum. Please direct me. I fixed the misfire.
What's normal current? What are your symptoms? Not enough info to help
@@ScannerDanner I posted in forum. Dugy401978 posted a picture. 0-1000 normal.
Iac width point 36.98%. Iac total airflow 0.14498 oz/s. That’s all the info my scanner gives me. It’s a two wire plug. I’ve looked for info on if I can test with multi meter. And what those readings should say. Sorry to bug you. Truck runs good since getting rid of misfire by changing plugs. I do have a bad o2 sensor. Fixing to changed those.
Need help!!!! I have a 94 dodge ram 1500, I replaced the motor and transmission. I do not have a scanner that will read live data. It will not stay running, I must admit I am no mechanic I have replaced many parts in hopes it would b one of them. No luck! I am getting a code 37 which is a torc temp sensor could this b y it is not staying running or am I missing something else. Please help I enjoy this old truck and want to b able to drive it again
Been having issues with part as well, went through 3 vtec solenoid pressure sensors on one and two on another before going for a dealer part. Its aggravating b/c you pull oil pressure, put a trigger light bulb on the solenoid and switch while driving to make sure and its confirmed another bad part. Or you send it off with a customer then part fails and the shop looks bad and you do your diligence to confirm the issue and ends up being the new part. Thanks for giving your experience and knowledge!
There’s a a note in the Service Manual of this car that says: “The Adaptive must be learned before the PCM will run the Mis-Fire Monitor. The PCM updates the Adaptive Numerator at every key-ON, and is relearn after battery disconnect. I’m not sure what that mean…
See video at 12:20 - ‘dimensional Reach is different on autolite vs OEM plug! ‘ Misfires on #2 were due to good looking plug of different length dimension from OEM . but that bad dimension on the new non oem plug causes that #2 cyl and its injector to misfire. This diagnosis by SD tells me not to trust the aotoparts store saying autolites can replace the oem-recommended plug. . . I’m curious why the DTC code wasn’t I’d ing a P0302 misfire. instead of 00300 ?
👍had a 07 CRD Jeep Liberty that broke some rockers due to a timing belt failure. No injection pulse until everything was reset. Found out the hard way on that one.
My truck (2014 Dodge Dueango) had the same problem where it would shake when in Idle and especially when we had our AC on. It showed it was misfiring on cylinder 1 and he couldnt figure it out until he found a tiny hole in the coil boot. He replaced it along with the spark plug and that was the end of our problem. Truck has been running great and hasn’t misfired ever since. Hope this helps anyone.
Dan,i think it must've been a patriot you are talking about with the 2.4l.On these 2.4 i get alot of these 1/4 cylinder misfire.especially on the avengers and so forth.when that memory reset dont do the job i do the enumerator reset/clear function and it has you drive the vehicle from 10 mph to 40 mph.it never says complete on my launch.but it always works.since on some of those engines it dont give you ckp/cmp function like that Durango did.thank you for your vids.i learn alot.
It's 12:56 Friday afternoon. OK to sit here and wait for 11 hours? I might have to bring my Galaxy Note 10+ in th bathroom, though.
That was disconcerting... it sounded like Herbert from Family Guy was going to do the intro!😆
When you cleared the "adaptive numerator", it lost it's ability. A couple long decels from like 80 mph should wake it up . Great video
I've used Autolight iridium plugs in every chrysler I've worked on, and never had any problems. What you did comparing the sizes was smart, and is a MUST befor installing replacement plugs . These auto part stores have there spark plug interchange numbers all jacked up, they will tell you a copper plug will work on most engines. 🤦♂️
I put a cylinder head on an early 2000;s Honda. Initial issue was a valve and seat failure with a low compression misfire. I finished the job and it ran smooth as glass. However it kept setting a misfire code on the originally bad cylinder. Flashing check engine light ect. I reset the engine adaptives after an hour of scratching my head and it eliminated the problem. I am hypothesizing that the misfire came on so slowly the adaptives learned the misfire as normal operation, and the cylinder suddenly operating differently flagged it as a misfire.
Disconnect the battery
Auto lite plugs suck. I’ve traced a lot of idle only misfires to many times an autolite plug. I’ll swap it with another plug retest and issue moves elsewhere I then condemn the plug and recommend the right plugs. Or a hey my car keeps going through coils what’s wrong? Uhm hey it could be these cheapO spark plugs. Love the channel, been seeing more and more crappy parts these days does make the life harder.
I see the Chrysler PT Cruiser through the Durango's door window, Danner! I am pretty sure its there for some misfire or no start, no crank issues as well😅
In youth working with my dad we never used anything but Champion spark plugs except for Delco plugs for the awful SOHC Vauxhall Bedford slant 4 and Bosch for Mercedes fintails Later I switched to mainly using NGK.
Love the XK150 quietly sitting in the corner istr Champion plug for those was N12Y
My bet is on a leaking fuel injector
Leaking injector would cause a completely different looking spark line 😉
Back in the day, I had more issues with Champion plugs than Autolites in the 3.5s. Cars that had "blown" tranny after tune ups all had Chmpion plugs.
I’ve been screaming plug at the screen during installment one of this saga. I recently had (and have had) poor Champion plugs more than anything. Most recently, a freshly built motor from a (supposedly) reputable shop in my area. I chased what I thought was an issue with the aftermarket fuel injection system (that’s what the shop chalked it up to before washing their hands of me). I had it to multiple people who made much needed improvements to the install, however, it was not until I dug into it myself that I discovered a CRACKED PLUG!!! Likely been cracked since installed by the shop as it was hidden snugly behind a header and someone probably smacked it with the socket when removing it.
Threw in a fresh round of NGKs and ran beautifully.
The Bad parts thing is A True Major problem. Even for someone like me that now doing things on the Side. Frustrating for sure! And Autolite? Really. Whatever shop put them in , shame on them.
Nextime you Get Gobal Disable stuck power off the scan tool and do a Full System Reboot plus use a scan tool other than a Snap on Spanon really likes to lockup try using a scan tool like the Think tool Pro units try them much better scan tool
Hi paul .i belive the igf generator tide on the igt line inside the ignitor gives the unreal misfires at the en of the video....as its not the acctual confirmation....saw the drawings on a toyota page...maybe working the same way
Cool intro, Caleb whistling & SD singing "we're back", Love it😍
This case study was great👍
The only thing I'm wondering is that how would the live data on an Autel scanner respond to the parameters reset function, just curious😉
Special thanks to Caleb Danner & James Danner👍
Stay Safe Guy's❤
I wont fit any electronic parts unless they are dealer parts,
Ive seen even good brand like Bosch work but not work 100% and cause problems, there again 99% of European bosch parts 5 years ago were made in germany, now they make them anywhere thats cheap martial / labour so eveything is just crap,
Ive seen copy NGK spark plugs, no telltale signs until they snap in half when you torque then up,
its causing us a headache and to much time
Had a problem with plugs in the 80s with champions there would be 2 or 4 bad plugs in every set so I went to NGK and Bosch
I've seen milage and cycles be required for a ECM to completely become operational. And both being options on the same car. I've done some "what if's" with one car in particular and it was extremely consistent with the FSM information.
I just realized that @scannerdanner looks like Triple H from wwe!
Thanks for part 2, keep up the videos we all appreciate them!
Who should pay for diagnostic and changing out bad new parts? It's so prevalent it's ridiculous.
in ran autolight xp's grandcaravan for over 10 years no problem i never read that they only make for 1 company
Paul this one for you...At the end of the video the misfire is gone but the scanner is still reporting....some ignitors have an inbuilt igf generator to comensate for timing delays i belive .hence the computer is not seeing the real igf signal but the generated one ..saw this on toyota design ignitor
I don't know which part is better the repair side of the video or the spider side LMAO.Another great video Danner boys until next time stay safe.
Great Video as always. Nice to see you talk about false miss fire data getting corrected with re-learns. Have seen it here and there. A little confirmation from another source is great. Kind of weird that it is Chrysler that keeps a memory and a good signal can be corrupted by it's adaptives. Reminds me of early OBD II days when people used to disconnect the Battery to clear the Light and (I believe) Chrysler was the worst at learning bad signals to be good. Made troubleshooting a bear... Kind of Curious if the P0302 was a Permanent Code. (Did no pay attention to the year.) Normally when basic codes are cleared, the Fuel, Miss fire, and Component Monitors are set at Key on. Permanent codes keep one of them from being set until a Drive Cycle or 2 has been run without repeat of Code.
I can't wait and I'm going to throw into the hat a faulty injector that isn't injecting at times so the cylinder hasn't got any fuel to ignite thus cashing the secondary ignition fault.
This particular issue (no fuel misfire) has a completely different looking spark line characteristic 😉
@@ScannerDanner thank you for the personal response 😊
@@johnmorton5498 of course! If I had the link, I'd share it with you
Type is secondary ignition common faults on my channel
I love diesels. Lol
Google says Chrysler Misfire Global Disable happens when the fuel tank is low. Not sure if that makes sense, but there isn't a lot of info on misfire Global Disable
Test suspect plugs in a Champion spark plug tester. I've had great success finding cracked ceramics in the tester.
Same thing when I find autolite or or Bosch plugs in a Toyota, factory plug are a must.
The reason for the Reset fixing the issue is the Crank Cam has wear on it and the timing gets off resetting the Memory forces it to relearn the new position on the timing so the computer learns the new worn position on the timing System Basically the timing as the Engine wears needs a reset even GM has this issue
why would brand plug matter. i agree with you but with the knowledge we have any of the plug companies should be able to make a plug that works great.
Great who done it video. Chased the new parts rabbit down that hole numerous times. Frustrating as hell. I have got to get me a Pico even if it’s only a two channel. Is your brother in the auto restoration business also? Cool cars in his shop.
If I pull out the lab scope to look at a single cylinder miss fire i always use at least 2 channels to compare to a good cylinder! I how ever don’t get to use the scope that often the place I work kinda steers me away from using it :( just because of the time it takes but Your videos are very helpful and are getting me a little more proficient at it!
