1985 TRANS AM EGR & START PROBLEM

Hi, I have a 1985 Trans Am with a 5.0 305 cid TPI, VIN CODE 'F". The engine light comes on. I scanned it with a code reader and code 32 (EGR) came up. I cannot seem to find the EGR valve on this car. Can you tell me where it is located or if it even has one? One of the local auto parts stores seemed to think it might be underneath the TPI MANIFOLD. Can you advise me on the location and what it would consist of to change it? Also this vehicle starts right up when it is cold, but has a long cranking problem when it has been driven awhile or is warmed up. Any help in this matter would be greatly appreciated. Thanks!

Start by checking fuel pressure and for lack of spark before you throw parts at the problem.

Always start with the basics or you will spend more in throwing parts at this vehicle than it could ever be worth monetarily.

The EGR valve is likely under the TPI runners as you were told. However, it may not be the problem. The vacuum solenoid or other parts of the EGR system may be at fault or there could be other mechanical problems.

As Bigfig stated, make SURE thats it before you go changing it. A handheld vac pump will allow you to discover if the diaphram is bad in the EGR. The valve is indeed located under the TPI runners. It is also a first class pain in the ass to replace without removing the intake. IT CAN be done however. Prepare to curse like you have never before and find out you CAN bend that way....

Make sure you check the vacuum tube and connections to the EGR valve. I believe it's a small plastic tube with rubber connectors, one at the throttle body and the other at the valve itself. If the rubber's cracked, that may cause an EGR code.

If you can get your fingers or a mirror under the EGR valve, you may be able to feel or see the diaphragm move when you apply vacuum with a handheld vacuum pump. They are about $25 at Autozone, I believe.

There is also an EGR switch, if I recall correctly. I think that vacuum hose may run to that before it goes to the EGR valve itself. It's been a while.

Good luck! KennyH
