Electronic EGR

PONTIAC FIREBIRD

I own a 1992 pontiac firebird, 163,000 mls. The question I have is regarding the electronic egr. My vehicle is equipped with a 3.1l v-6 with crossfire fuel injection. The egr is located underneath the crossfire injection. Do these egr's go out often? If so, what is the proper method for removing the crossfire injection system so that I can get to the egr? I have a haynes manual for the vehicle but it truly doesn't provide much detail for this application.

I bought the vehicle to restore. Purchase price was 900.00 and its runs fantastic. It had sat in the person's driveway (uncovered) for 4 yrs, had a dead battery and a flat tire. Aired the tire, put a charge to the battery and she fired right up. Not a problem since. Now its getting time to get it emissions tested and i'm not sure if she will pass, thus the reason for the questions. I have priced new egr and it is in the $350-400.00 range. Just would like to know if this is something that I should consider replacing and if so how to do so. Thanks. :)

So you are getting a service engine soon light with a code for the EGR? If not, why are you wanting to replace it?
Second, the crossfire injection you are refering to having to remove is the air portion above the fuel rail?

No check engine light appears, and I was merely curious how to replace the egr if necessary. The exhaust doesnt smell right so I know there is a problem. Do these electronic egr's go out like the manual ones on other vehicles?

They do go out, but the computer is pretty good at faulting them when they do. If you are smeeling exhaust smells, then you may want to look for a leak or something.
Im not sure of the year they went to just looking for the service engine soon light as all they test for on later model year emissions. If they have to test the exhaust, just make sure you run it for almost an hour at 60 mph or above, then go directly and have it tested.
