Wow this video answered all my questions regarding EGR and how they are responsible for my car's stalling when it gets hot. I just it replaced on my 1996 Camry. Your video is straight to the point and very informative. Thank you for uploading it!
What size is your engine?
This was actually really helpful. Thanks man. I was pretty sure my bad acceleration and funny exhaust smell was my EGR. I watched this video then started my car and opened the hood, looked at the EGR and it's clearly leaking fuel. Cheers. Thanks.
Exactly whats happening to me bad acc and smell
Exact knowledge shared, detailed information, and right to the point. Just gained a subscriber. Much Thanks!
Excellent video and content. Professionally done with easy to follow and right to the point explanations.
Thank You.
I appreciate this, thank you!
Damit Boy..Clearly Exsplained.Yes Sir...Straight to the Point. 👍
Nice, short, informative video. Thank you
Short but very useful video! Great job my friend 👍👍
Thank you my goodman!
EGR doesn't reduce charge temp, it increases it (exhaust is always hotter than intake). This is why there is often an EGR cooler for higher load (hotter exhaust) condition. EGR reduces the oxygen mass in the cylinder charge, reducing the ingredients available for NOx to form, whilst also giving any results of partial combustion another chance to combust.
Only partially correct. EGR gasses increase the charge temp, but they decrease combustion temp (which is what he said) by introducing decreasing O2 content and thus altering the mixture ratio to not burn as efficiently and as hot.
Introducing already burnt gasses into the induction manifold means that when the contaminated charge does burn it will burn cooler - it is the heat of the burn that makes NOx. Having the EGR valve stuck open will not affect high rev performance because the valve opens at higher revs anyway, but at low revs the stuck open EGR is like having a leak in the inlet manifold, which will cause lack of power and rough running, and be more likely to stall the engine.
My egr was bad, car idled funny and really noticeable at 50 mph plus, had it on cruise control and you could hear it rev way up and down . So bad some time felt like it would quit, then engine light came on. Opened hood my eyes started burning. So I took egr out I noticed look liked it leaked some fuel. The plunger seemed to work and if I pushed in and held finger it stayed, but I replaced it any way thinking maybe carbon upped or something. What a difference it runs like new, glad I risked the 60$ .
Amen to that. With love and respect is the way to go.
Good video. Just replaced mine. Video sounds like it’s narrated by Lars Ulrich 😄
Thank You, sir, very educational.
Engine misfires can also be a clogged EGR Valve .
Gotta chuckle out of this video. How diesel and gas engine issue symptoms are mixed together instead of fuel specific. NOx is pretty much a diesel thing. But what really got me was how many times it was stated that the exhaust cools something. Then says the exhaust may cause unexpected combustion due to too high of temperatures, causing engine knock. In a diesel, sure. Cause they don't used a spark to create combustion. This would be a good example of why people shouldn't just copy down a bunch of info, mash it together and present it.
Excellent job
Such a well explained video. Thank you.
Glad it was helpful!
amzing video for education!
Great video! You have a new subscriber in me! Right to the point video. Perfect!
You are the greatest!
I didn't have any of those symptoms with my 19995 Toyota Camry no codes either...my car would drive perfect then when I got to the light it would shut off causing a nasty smell..it would turn on with no problem ..I had no codes on the car my mechanics couldn't come up with what the problem was ..one muffler guy told me I had to change the cat and it would cost me 500 ..my regular mechanic told me a clogged cat wouldn't cause the car to cut off .. anyway I put in cat cleaner fuel injector cleaner nothing helped until one day I was coming out of a AutoZone and a street mechanic asked me if I needed anything fixed I told him the issue he smiled and said how many guys told u it was the cat ...he said on these cars it's this right here the erg valve..he's said u can test it clean it or disconnect it but if u disconnect the check engine light will come on ...I said are u sure he said my brother had the same car same issues he spent over 600 trying to fix it until someone told him what it was...I brought the erg valve went to my regular mechanic he put it on for 75 dollars because he had to take of the whole back line to clean and check it ...car fixed ...
Great video
definitely gained brain Rinkles i appreciate the lesson
Thanks!
Too generous, thank you!
Outstanding information!
Very nice thank you!
Nice vid... can the power train warning light also light up (instead of the engine light) if you have this EGR problem?
2001 Chrysler Voyager how do you know if it's the egr or Cadillac converter. Have a strong exhaust smell motor hard starting and runs ruff .
you know your stuff.
Thank you
And thank you!
You need more exposure…great easy to understand video
I appreciate you, thank you!
04 civic lx throwing a P0420 code for the cat and failed emissions. Is it possible it’s the egr or the actual p0420 cat code ??? Thx
06 TL, i did a major service and still have a new thermostat and egr valve that i wanted to install. When im in park my car jumps around 300rpms every 30 seconds or so
Would you also be able to tell if its a bad EGR by unpluging it? I did and my iddle is not hesitating rightnow. But does that affect the engine? It also is not throwing me the codes you mencioned above but it certeinly seems to be this
got a 2020 wrx just hit 21k miles and so far i have a rough idle bad acceleration and three codes random misfire p0402 and p0171
Straight to the info. good video. thankyou
and thank you!
Can you do a air pump check valve next? (P0491 secondary air injection)
I’ll make sure to add that on my to do list, thank you for your suggestion!
My 02 xsterra keeps stalling and won’t start is this a bad EGR valance issue ?
Ware is it on a 2011 Subaru Legacy 2.5i? Or is it all Vac lines?
My honda crv 2010 car scanner shows egr err 99.2.I cleaned the valve but still shows the same .Do I need to change EGR valve? I eagerly waiting for your reply.
Thanks.
Once the dealer updated my computer on my 2004 dodge ram 1500, I can't change the egr myself, because now, unlike 7 years ago before the update, you must have the $40,000.00 computer to have the truck computer recognize the new egr. I learned this the hard way this week, as I installed the new one (just like 7 years ago), and it wouldn't turn over until I had it towed to a shop with the dodge computer. Pretty soon, you will not be able to replace any components on your newer vehicle unless the dealer does it.
Hello and Help!!!
Thank You for breaking this down for me. Code came up as EGR valve for my 94Celica 1.8. The engine in your vid looks almost identical to the new one that replaced my original. I'm having a really rough time finding this part. You mention cleaning it as an alternative. Which cleaning product were you referencing for that option? I am so desperate to fix this issue. My car was my favorite everything and lately it's become a stressed out burden.
Thank You for your time!
I saw a video on UA-cam they cleaned with soap water and tooth brash
My nissian note drives and shut off after long drive once you slow down it starts to buck and then shut off change the throttle body same thing happens...any suggestions
I got a 05 Ram 1500 5.7 with code p0457 when I come to a stop or light rpm’s drop a little bit when I let off the breaks rpm’s shoot back up and truck runs fine any guesses my your tubers
My Ford explorer 2006 exhaust sounds super loud…could this be a symptom of a bad eye valve?
Would a faulty egr valve cause excessive white smelly smoke from the exhaust upon start up but clears after about a mile of driving. 🇬🇧
Hi i am using opel 2002 2.0 diesel it has no power when i drive upside what should i do
Can you do a bad fuel pump
Can faulty AGR causes fumes from the back of the engine?!
I have a p04040, car runs and idles fine. My problem is I get an intermittent old nasty smell mainly with the sunroof open only. It's not the HVAC system, could it be the evap? Thank you in advance.
Maybe a clogged catalytic converter. Rotten egg smell?
This has to be my issue replaced the spark plugs and o2 sensors and still have those symptoms yoy have described
Was this the problem?
I have a P0401 code on my
2004 Ford Escape 2.0 A/T
Is this the culprit for my car stalling when doing slow turns especially in reverse and when the AC is on?
My car does this in reverse.
Can this cause the injection fault light to come on, and cause the motor to go into limb mode. Decrease of power. Suzuki
The purpose of the EGR valve is to destroy your engine over time.
Have you deleted it? I’m thinking about it but not sure if it will cause more problems. I got a 95 mustang 3.8 Essex v6 ohv. Let me know anyone. I only have a egr code and that’s it. I’ll clear it. Stays off then comes back on.
@@classicv8dude268 (I have a Mazda turbo diesel ute) Same I have been thinking about deleting the EGR valve but doing a Google search they say it can cause more problems, hotter burn even cracking the head.
@@12volthighpeakvanlife.62 Yep, same.👍
Same for the cat?
@@classicv8dude268 I have 2 80's lincolns and I can't have any vacuum to them otherwise they run like shit. I'd say you're safe but you may still get a code.
An EGR valve from 1992 should be cleaned or replaced?
I have a rough idle. My car is also sputtering. Check engine light is on. I did a smoke vapor test and noticed a small leak from the gasket of the egr valve. I cleaned the throttle body real good. That cleared the check engine light but it came back 20 minutes later . Could the egr be causing these issues ?
Mine was doing that too I was stopped at a light or something like that and then it would be revving up really high and it would just go up and down up and down like she was choking
I have problems with my Vauxhall Tigra A. Sometimes the throttle doesn't responde as it should at low RPM's and sometimes cut's off also at low RPM's. Also the oil is leaking at the plug where I pour the oil in to the engine probably becouse the compression is bad. I will try to change the EGR and if that doesn't solve the problem than I think I should change the car lol
What kind of car is a Vauxhall tigra???????
@@jasonsnider8749 It's a coupe from the 90's 😀
For Hemi owners 08 and above. Can someone confirm that they don’t come with and egr valve. I’m really at a loss here. Trying to figure out what is going on with my WK.
What is poo3d?
Hi, I have a 1.6 2010 focus TDCI. I had the EGR replaced 6 months ago as I kept getting acceleration issues. The problem improved but it still happens, usually when on the motorway after about 10 miles, around town it's fine. I have a scanner and it says the EGR is stuck closed but if I stop the engine and restart it straight away the problem goes away for a while so my question is, can anything else be faulty? I would have thought if the EGR is stuck closed it would be stuck permanently? Many thanks.
Hello @lusiscus. Any luck u got out of it. Or did you get the EGR Valve changed/ Cleaned ?
I believe my egr may be stuck open it’s saying bank 2 or sensor downstream
That's what I got
Same symptoms in every way...
Those are meant to be thrown away when you first drive off the dealer lot.
Just bought a new egr valve and egr tube and the light comes back on. Can I test and see if the new egr valve is bad? Car runs great. 2008 equinox 3.4. Thanks
try reset ecu...some vehicles need to run a few miles to reset though
Take the battery wires off the battery touch them together for 20 seconds connected back to battery
@@jayskrills7375 what does that do? I already had the codes cleared
@@thebeddoctor4273 that resets the ecu
@@thebeddoctor4273 that should shut the light off
Will a bag egr valve stop your vehicle while driving?
Rarely, but no
Hi. I've got an unmodified 1998 Nissan Pathfinder, 164,000 miles, 3.3L V6, 5 speed automatic transmission. Owned by an elderly couple...treated well. Runs smoothly.
10w-30 oil/filter is new and full. Same with transmission fluid.
When it's first started it knocks or loudly rattles for 3 seconds. Then it stops. Once warm it will only do the startup rattle about 50% of the time. Exact same noise returns from about 1,800 to 3,200 RPM and then stops. Also, the noise quiets and sometimes disappears between 1,800 - 3,200 RPM if I let off of the accelerator and coast. It also will not do it sometimes if I'm going up a steep hill slowly with the RPMs are in that midrange, under the hill's load.
The noise increases in speed and loudness with increasing RPMs. It sounds like 1 or maybe 2 cylinders of the 6, to me.
The main bearings and rod bearings were changed. Looked good, some rod bearing wear on a couple but not serious. No rod or crank shaft slop was noted before or after replacement. Made no difference in the noise. The crank was NOT sanded/polished.
It throws a P1400 code for EGRC Solenoid Valve error. I don't notice any idling or power issues though. It returns within a few minutes after clearing the code. Could this cause a knocking noise at certain times like I have? It runs smooth cold and hot.
I've narrowed it down to 5 things based on its part time occurrence:
1. Flex plate?
2. Timing belt tensioner failing (unknown when last changed)?
3. Torque converter?
4. Hydraulic lifters?
5. EGRC Solenoid Valve?
I have two short videos I recorded it and can share if you want to hear it. Thanks!
Sounds as though these valves are more trouble than they are worth!
My engine light is on diagnose shows egr valve
Price is over $350
Today will replace and see what happens
95 Lexus sc300
My car is vibrating when I drive and I think the speed idle is not moving I will look at it today again
What ended up happening? I have a 97sc300 and would have vibrations and rough idle but it’s because I had a vacuum leak. I fixed it by replacing the intake and runs a lot better now. Js want to know about ur problem so I can prepare for it in case my egr is bad 😹
Can a bad egr cause power cuts ?
I have a Mercedes Vito. When the EGR is dirty is can inform the computer and it puts the engine into “limp” low power mode. If I turn the engine off and back on it normally clears it. But ever so often it needs a good clean
No it will run much better when blocked off or removed.
my car smells like eggs when i gun it
You have a blocked cat converter.
The moment I connect EGR it kills the engine it stops
👍👍👍
Can a EGR VALVE be bad without throwing a code??
Following
next week i ll go to clean mine at mechanic, car, when downhill and lightly press the acceleration pedal, is doing a wobbling thing, like when you unproperly lift the clutch pedal. is very annoying. all this only downhill,
I had a 1975 twin cam carburetor engunn that ran for 20+ Years with non of this Garbage, didunt run hot OR Knokkéd Evér
u don’t need one unless you’re towing
So this is what’s wrong
NO POWER TO EGR VALVE
Get rid of EGR its just trouble maker nothing more
Just shut it off because it will destroy you engine!
