i have a 91 gta trans am. its drives just fine but when i hold the same speed for about 5 to 10 minutes on the highway it will throw a check engine light. if you turn off the engine and start it again the light will be off. i hooked up a scanner to it and it said that it was a code 32. which is eighter a bad map sensor (which was just replaced before i bought the car) or a egr problem. do you guys think i should just replace the egr valve and would that make the light stop coming on?

 

That is a EGR problem code.. could be caused by many reasons... I took my egr system out completely, got a block off plate, and got a custom prom burnt from TPI PARTS.net. I got a few other things changed as well while they were doing the chip for me... Such as fan temp., smog delete, egr delete, rev limiter, top speed limiter delete, and a few other things that I can't remember. I don't know where you live but in some places where they do smog inspection you will probably fail if you remove the EGR. You'll have to check your local laws.
good luck

Here's a chart for the code 32. Should get you going in the right direction.

 

so it says by code 32 thats its an egr circuit or whatever. do i gota do alot of wire work or could i just replace the egr valve and would that correct the problem

 

I had the same problem with the car in my signature. It was a lazy 0-2 Sensor that was the primary cause as well as the EGR solenoid by the distributor. The electrical plug was broken and was not making good contact. The code 32 is a bear to troubleshoot....have patience.

 

K thanks. how easy is it to replace the egr solenoid? and is the part expensive?

 

Not hard to replace. Mine had two small vacuum hoses and an elecrical plug that had to be removed/replaced. I went to a pick and pull salvage yard and got a good one for $10.00. The single 02 Sensor on the drivers side of the engine was a one wire application. With an 02 Socket and another socket to couple the replacement was easy. Took about 30 minutes for both. Good luck.
