no more EGR ??

[orion]

Can our 3.5s live happily without the EGR and the holes capped off? i know all about the emissions concerns, but we don't get tested here. i had an AMC eagle with idle problems, removed and capped the EGR and she ran great for years. with it being a problem spot for us, i thought just remove it. or maybe i'm just crazy? please help.

try it unplugged and see.

For one thing, your check engine light will always be on, so it won't be able to alert you to any new problems that may arise.

There is also the potential that not having EGR for a long period of time could put your engine outside of the operating parameters it was designed for. This could be something as simple as running lean on the freeway for a couple hours and burning a valve. It could do nothing. For this engine, which was designed with EGR in mind, I would leave it on there. That's coming from a guy who is also in a non-emissions state and have run vehicles without catalytic converters or emissions pumps.

I'd have to check to be sure, but the addition of the exhaust gas to the intake tract also helps to keep cylinder temperatures lower. This could be a matter of keeping the miture from becoming too lean, or it could be something else.

I say keep your nuts tight and leave the EGR valve in place.

I would be hesitant to remove it because, as mentioned above, our engine was deveolped to have an EGR system from the outset rather than added on to meet some Federal mandate. Even in other nations with different emission requirements the 6VE1 still has the EGR system, which IIRC complements the variable-length intake runner design.

Of course we're always interested in the results if you're willing to become the guinea pig.

Thanks you guys for the feedback. i think I'll be a good boy and leave it alone.

The EGR valve is closed during idle and full throttle operation -so I could see where you'd want to remove it to improve performance. However, its benefits would be outweighed by all of the problems that would arise during its absence.

So could my EGR be bad then? its giving me a reading of too lean and my check engine light is on and its running rough and sometimes even stalling,,I have no idea how to fix that

[mbeach]

Clean it out and see...
There's a dozen reasons why you could be running lean -a stuck (open) EGR would only be one of them. How's it run at cruising speed?


It looks like you are looking for some (musical) gigs -what do you play? I used to be a (fairly) well-respected bouncer at the Frog, Bear and Wild Boar Bar -maybe I could call the guys and put in a word for you..?

[thedutchguy]

don't forget that the egr is there for reducing nox in your exhaust gasses by reducing your combustion temperature!

that would be awesome if i could play there,,ive already played at Kafe Kerouac and Thirsty Ear here in columbus,,i used to play all over Dayton and other places,, just trying to break into the market here,,thanks mbeach I would appreciate that,,,if you can give me an email address that would be even better and then i can forward my electronic press kit to them www.sonicbids.com/darrenjones

at cruising speed it runs fine thats why i cant figure it out and ive already cleaned the egr
