OK, so I've got a 91 Sunbird with the 2.0L. I've gotta pass an emission test, so i've got a new cat and muffler to put on the car, and today i just installed new plugs, wires and O2 sensor. I would like to clean or install a new EGR but I don't know where to find it, and i'm not 100%sure what it looks like. I've got this picture http://www.rockauto.com/ref/ACDelco/Detail.html?214-5076.jpg but it doesn't show where it is, can anyone help me find it in my engine bay?

Ok its kinda a PITA to change but not that bad and its located right on top of the intake manafold. here


its the copper looking thing under the fuel rail, with a vacume line goin to it.

and is it fkin up, what state do you live in. it should pass emmisions.
HELL if my 2.0 passed with a dead Cyl and a blown head yours should fly right thru.

I have a 91 sunbird so I am assuming yours has a throttle body? If so, It is located under the round air clean on top of the throttle body. The EGR Valve is located between the throttle body and the valve cover on top the intake manifold. The picture that you have is exactly what it should look like however yours could be a goldish bronze color. To check it (make sure the car is off), stick your fingers in the holes on its underside and push the insides to see if it moves up and down.

It easy to change on the 91 if you have the throttle body. There is not much in your way.

91 and up are MPFI.

OK, i took a picture, and circled what i think is the EGR, feel free to correct me if i'm wrong.
Also, how easily should I be able to push the valve in and out?
And yes, I don't have an MPFI motor

Don't know if this link will work in anything other than IE, it's my msn space

So, I bought a new EGR valve, bc I figured the one on the car has never been replaced, and hey, newer is always better, in most cases, and now I've just gotta let my engine cool down, and then i'll go throw in the new EGR. Anyone in the Ottawa, Canada area that can install a muffler and cat cheap and soon?

To properly check if the EGR is working. With the car running, reach underneath with both hands and push up on the diaphram. The car should stall out and die. That means its ok. If it aint broke, dont fix it.


you snooze you lose!
keep working, millions on welfare depend on you!

92 and up are MPFI most 91 models if not all (except turbo) are throttle body

All 3.1's were MPFI.

Meh, I figured because the O2 sensor had never been changed, I'd swap that, and the plugs, and after seeing those, I figured the EGR should be done, I pulled the old one out and wow, it was disgustingly clogged, so it's better I did it now, at least I can Pass the Etest now, well, after i get the new muffler and cat installed.

I guess lol, E tests can be a real pain in the ass.

thats for sure, i've had the car for about 2 months, and i haven't been able to register it bc i couldn't get an etest, good thing i had a plate on it though, but it was expired, lol

How would you go about changing a pcv valve? i just unhook it and put the new one in it's place?

Pull hose off containing PCV valve from the valve cover. Pull PCV valve out of hose. Stick in new valve. Push hose back on valve cover.
