can someone post a pic of a 2.8l camaro (mines an 87) engine bay, and point out where the egr valve is i have a bad bogging situation at low rpms and i heard that may be due to the egr valve but i cant find it if someone can show me where i would be so greatfull thanks guys

 

i noticed something that looks to be the egr valve that is to the left of the main plenum kind of by the a/c freon tank (to the south right of that) is this it?? thanks

 

If your 2.8 is like my 5.7 (yo, I'm twice the block you are) the EGR is under the plenum, bolted to the intake.

 

lol IM also twice the block I am lol ( I have a 94' z28) haha i use the 2.8l for gas mileage (when its on the road ) Thanks ill take a look today im hopin its the egr

 

ok i know i have to take off the plenum but do i take all the top bolts off and take off the top half or shoot for the lower bolts and try to take off the entire plenum to get to the egr? i started taking off the top bolts and realized that that would only get the top half of the plenum off (and if i do that i probably need a new gasket right?) thanks guys

 

It is on the passenger side exhaust manifold, next to the plenum.

 

thanks alot, what exactly should i do to test it? if i hold that hose there is no pressure and it doesnt change the running condition should i change it out?

 

The hose should not have vacuum at idle. The egr is only supposed to open when the engine is hot and the tps voltage is higher than idle. Take the egr off and see if it is stuck open, usually carbon from the exhaust. you could try cleaning it or just replace it. Or do what I did, make a block off plate for the tube that goes to the plenum and not worry about the egr anymore. No emissions testing where I'm at, just have to pass a visual inspection.

What exactly is the problem you are experiencing?

 

ill post what i wrote from another thread

ok i've been tackling this problem for a straight week now, problem arose on the road when all of the sudden i lost power, i pulled over still running and ever since then if i give alittle bit past idle to 1/4 throttle it just bogs horribly and POPs, if i give over 1/2 throttle to full it doesnt do this tho, i changed the spark plug wires to no avail, i also noticed my guages fuse blew when i checked all the fuses so i replaced today and it popped again in about 1 minute! it this some kind of wierd short? i already checked all grounds cleaned them, i'm at a loss please if anyone has any idea just lend me some advice i would appreciate it so much


thanks for the help

 

Double check all the vacuum lines too.

 

cool lil diagragm whered u get it!? lol i checked and re-checked all vacuum lines i could find but ill use the diagragm to find everything and check yet again, how do i get the egr off to see if its malfunctioning? thanks again for all the help

 

This doesn't sound/seem like an EGR issue. Also, what fuse blew/keeps blowing? Is it marked "gauge/panel" or another?

 

thanks for the reply, yes it is the gauges that keep blowing under the dash do you have an idea what it could be?
