EGR removal?

[ikeyballz]

i was on a site and it said that removing the EGR causes your engine to heat up?! it said the egr prevents a little combustion so that it doesnt heat up as much... anyone know anything about this?

[poormillionaire2]

I could see that as being true. EGR displaces some air in the combustion chamber for a comparatively smaller combustion process. So, replacing that exhaust with more air (and fuel) would yield a better/bigger combustion process. I can't see it making that big of a difference as far as heat though. The EGR shuts off at WOT anyways so it wouldn't be any hotter/cooler there either.

ic... anyone who did it before?

hard?easy? im gonna do the IAC, so i figured while im at it i might eithier take out or change the EGR valve..

The EGR is your friend, unless it's broken, then I'd suggest leaving it alone. But it's up to you. If you're really curious, try taking it off for a while to see if there's any noticeable difference.

I do believe without some flinagleing (tuning otherwise) of the PCM, you are going to have some issues.

im sure it will make the car ride like ass! u cant take anything off and not have something go wrong....

if you replace the exhast with long/short tubes and a new system, doesn't that remove the EGR system?

[philly rs]

he didnt say he was gonna do all that, im taking it will somehow be deleted...unless im not awake enough, i could be brain dead lol

I'm deleting mine when I get my stuff from Formula. I already have the blockoff plates, I just need to get to the header provision. Its a tight spot back there...

EGR deleat on an OBD II is a little bit more involved than on OBD I. You'd have to send your PCM out to have it reprogrammed (or invest in an expensive programmer). If you just remove the EGR you'll get the SES followed by reduced ignition timong and a loss of power.
EGR is actually a GOOD thing to have on a modern engine. It started out as a pollution control but car mfg's soon found out that it had an even better use..cooling the combustion chambers to combat detonation. If you modify an engine and deleat EGR you'll probably end up with pinging, and without EGR, no easy way to stop it.

Eh...I'm not worried, he's tuning it for me and I'm running a cooler t-stat. But you're right, its an OBDI car.

hmm ic. damn, i hate the thought of used up gas coming back.. but anyway, how often does those EGR's break down?

DAMN COMPUTERS!!!!!!!!!!!!

GO CARB!!!!!

haha i would if i had more $$ for the upgrades needed to bump the power back to EFI range, and if i had enough $$ for GAS. >_<
