My 2005 GMC Yukon XL had the exact same problem. I took it to a car repair shop, very reputable in our town, and they replaced coil number 3. I got out on the road and within 20 minutes it was misfiring again. I took it back and they said the coil they put on was defective and replaced it with another one. Then within 20 miles that one started misfiring as well. I've been searching the internet for a possible secondary problem and looks like I found it through your video. Truck is running like a fresh engine again. 240,000 miles and still a gem. Big thank you, Sir! Keep up the good work.
I replaced my wires and plugs and my 05 gmc thru the same code . I replaced the #3 spark plug with a good old sparkplug and walla problem fixed . New spark plugs can have a short to
I just had a similar incident. one of my brand new coil packs shorted out and blew the fuse for the entire drivers side cause if all four cylinders to not fire. All codes came back saying o2 sensors bad map sensor bad mass airflow sensor bad. Fuel pump etc. GM needs to make the fuses for individual coils. Instead of just one per side
Terence, You are dog-ass mean working in that ice. My hat is off to you! I haven't been working on my own vehicles since before the injectors. Just changed plugs, then got the engine light, then replaced wires. Diagnostic tool at the auto parts said #8 so replaced the coil. Light went off but three days later its back. So suspecting something similar. I don't think I'm up for this for fear of doing more damage than good. I have a way of doing that. Don't pay any mind to the "throwing parts" comment you got. Appreciate the video. Now I know what I'm gonna pay for.
Nice video, seems like you were able to sneak the injector out without having to remove the whole rail. If you can give some details, would appreciate it.
You can unbolt all 4 bolts on the fuel rail (2 on each side), then completely pull up the side you're replacing the injector on, (make sure to blow everything off first and not get any crud on the tips of the good injectors), and remove all the wiring on the ignition coil rail and then unclip the bad injector, wiggle it out, grease the o rings on the new injector, pop it in, clip it in place and reverse the procedure, making sure the side of the fuel rail you popped out completely pops baxk in all the way and none of the o rings slipped off upon removal
@@TerenceDIYi noticed that gas from the rail almost pinged ur hood mine doesn’t have that much pressure I changed the fuel filter a yr ago but it starts every time, should I b worried about my fuel pressure?
One of those codes is one of the front 02 sensors the p0420 if you replace them do it in pairs there are 4 02 sensors on these trucks 2 upstream 2 downstream atleast mine does
I have a problem with cylinder #4, checked by swapping wires - coils.. I will pull injector and try some carb cleaner Can't hurt anything for sure. Thanks for the tip.
I would love to help but I am backed up. Every since my dad passed a couple of months ago, I have gotten off track. I am finally making ground to get back on track.
I LOVE YOUR VIDEOS THE CAMERA SHOTS ARE EXCELLENT check the ASD RELAY IN YOUR FUSE IT HAS TO DO WITH A SIGNAL SENT TO THE ECM. JUST A THOUGHT SINCE IT CONTINUED TO IS AT THE SAME CYLINDER. ALSO ITS SAFER TO USE A SPARK TESTER.
Thank you for sharing your video. Gave me some tips for my truck. I have a 2007 Chevy Silverado 5.3 l. My truck runs rough in the morning or when it first starts. After it warms up it runs fine. Still trying to figure out what's wrong with it?... But thanks for sharing. I subscribe to your video and gave you a thumbs up... Watching your video all the way from Northern California the Bay!.

Hi Conrad, cylinder 6 is the 3rd coil on the passenger side. The first one on the passenger side is cylinder 2 for reference. 2,4,6,8 . If you have anymore questions feel free to ask. Thanks for watching!
@@TerenceDIY , Thanks. I took out those new, ignition coils because they were defective. Got my $325, back A.S.A.P., & put the old ones back in. Engine light went off imediately. And, no problems starting.
I’m having the same issue on my truck. Switched the coil pack, spark plug but the check engine lights keeps coming back. After you replaced with the new injector did the misfire continue? Not sure if you said in the video couldn’t hear if you did
Hi Diego, this new injector fixed the misfire instantly! If I were a betting man, I would place my bet on a bad injector. If you replace it, let me know how it turns out. Thanks for watching!
Terence's UA-cam hey I’m having the same exact codes as your Chevy except it’s on my Chevy express, cylinder 3 misfire and evap fault, did you end up switching out the evap solenoid and canister?
@@johnsmith6368 bra u must ain’t watch the video are you a little off or something. He didn’t throw not one part he used his code reader and solved his issue in five minutes u sound like a clown damn ifiot

Hi Ed, I am happy my video helped you. Thanks for watching!
It was the injectors?
Lmfao you didn’t even say what the issue was
I need to see how you changed it out without taking off the fuel rail… great job though!!
My 2005 Avalanche just throwing a P0305 code. I’ll be attempting to fix it myself this weekend. This video showed me what i need to be looking for.
I replaced my wires and plugs and my 05 gmc thru the same code . I replaced the #3 spark plug with a good old sparkplug and walla problem fixed . New spark plugs can have a short to

Replace that braided ground cable seriously corroded could be part of problem nice vid!!
Nice video, seems like you were able to sneak the injector out without having to remove the whole rail. If you can give some details, would appreciate it.
Hi Victor, You can replace it without removing the entire fuel rail or the fuel lines. Very easy job. Thanks for watching!
You can unbolt all 4 bolts on the fuel rail (2 on each side), then completely pull up the side you're replacing the injector on, (make sure to blow everything off first and not get any crud on the tips of the good injectors), and remove all the wiring on the ignition coil rail and then unclip the bad injector, wiggle it out, grease the o rings on the new injector, pop it in, clip it in place and reverse the procedure, making sure the side of the fuel rail you popped out completely pops baxk in all the way and none of the o rings slipped off upon removal
You should swap the injector with another and see if the code pops up for that cylinder.

Sounds much better, definitely hear the air leak though hopefully you found it?
One of those codes is one of the front 02 sensors the p0420 if you replace them do it in pairs there are 4 02 sensors on these trucks 2 upstream 2 downstream atleast mine does
420 is a dead cat. Due to driving around on the misfire.
Did it misfire while you were driving I have a misfire at 20 -at 40 it stutters and mises or feels like a jerk at 50-60-70-80-
Replace them all if ther on header exhaust been there aint cheap fix thogh easy to do also catalyst concerter are a big hit but do it
It's true, my I did the same to my truck.
Looks like your missing your plug wire metal heat shields. The rubber on the spark plug wires can’t handle the heat from the headers. Js
I have a problem with cylinder #4, checked by swapping wires - coils.. I will pull injector and try some carb cleaner Can't hurt anything for sure. Thanks for the tip.
How did you fix the problem?
pull the fuel pump relay to relieve pressure out of the rails
I have the same problem misfire cylinder 3.p0303 Did you have to do a relearn on the new injector?
Nope. Once you install the new injector, you will be fine. Thank you so much for watching.
@@TerenceDIY I'm in Dolton gonna buy 1 tomorrow with a misfire you up for the job?

My 02 suburban has misfire in cylinder 3 and it won’t crank till 2nd or 3rd crank not sure if it needs wires n spark plugs or a fuel injector
Sounds like you may have a bad ignition coil or injector.
If there isn’t a fuel injector code then it’s only a coil or spark plug or the wire
It Definitely Shock the Life outta me thought i was seeing them White Gates 😂 Rubber Gloves is the Way to Go Safety 1st learn frm my Mistake
thankyou sir for showing me were no#3 cyl is.my avl prob need coilpac.my scaner said 3cyl missing.

Hey Bro, where is cylinder 6 on your Chevy Express Van? You know, which ignition coil is consider cylinder 6?

@@conradsuddarth632 , that's awesome!!
Dang man ,good way to check it but it sounds like the engine has some mechanical issues, it may be just the sound on the camera
The engine had a slight tick, but other than that, it ran fine. Thanks for watching!

Perfect vid for my problem on my 2000 Chevy truck. Nice detail. SUB'D
I have problem with my 2005 chevy tahoe 5.3 misfire on cylinder # 6
what was the issue?
Me too I changed pack and wires still low compression on 6 2008 Chevy Silverado 1500
Great video man
You swap out those O2 sensor? That will also make your vehicle run like poop
I’m having the same issue on my truck. Switched the coil pack, spark plug but the check engine lights keeps coming back. After you replaced with the new injector did the misfire continue? Not sure if you said in the video couldn’t hear if you did

Terence's UA-cam light came back on after I replaced it. Now I’m lost on what it could be
@@diegobrizuela1459 can you send me the code that triggered the light, Diego?

Great Job T!!!!!!
Thank you and thanks for watching.
Good video help alot
Thank you and thanks for watching!
Thanks, video helped a lot.
Did you have low compression
Nope. It was just a misfire. Thanks for watching!
Ok I had a misfire in cylinder 6 with low compression ya good video keep em coming
Sounds like vacum leak
How do you know which one is miss fired
He had a diagnosis test and code for cylinder.
buy you a cheap code reader from walmart. 25 bucks or find a harbor freight
bob dan that’s a good idea. I didn’t realize that they were cheap
150 dollar DOLPHI INJECTORS
this is not a diagnosis this is you throwing parts at it till you fix it.
I can’t get a check engine light on my truck nor can I get a parts house to put their computer on it because of the covid 19
Did you see something I didn't? He didn't throw parts at anything. He found that it was his injector that was bad and he got a new injector.
@@billcoley8520 A simple code reader is pretty cheap now days and their easy to use. Even Walmart sells them.
