I have an 87 GT I recently purchased and haven't driven much at all. Here is my problem: the car runs extremly well until you have driven for a while and it's good and warm. The temp gauge reads around 180 and stays there. That's when the RPM's climb to around 2000 and stays there. I'm still learning guys, I need help! I was told to remove and clean both the EGR valve and the IAC. I CAN'T FIND THEM! I feel like an idiot![sm=bangbang.gif] Can someone please help educate me so I can clean these? Thank You very much!!!

 

The EGR is on the backside of the throttlebody spacer and the IAC is on the front

 

best thing to do, go to your autoparts store and pick up a haynes, DONT get a chilton

 

It's long gone now but I used to have an 88 with the same problem.

After fixing all the recommended pieces. I just gave up and drove it.
Flicking the key from off to run before it actually shut off. Would cure the high idle for a few days.

After finding the off, on key trick I refused to believe it was anything mechanical like a intake leak.
