1991 Camaro V8

I just got this car and it is idling very high, I took it to my mechanic and he said that the idle air control plug is not getting any power. He said that he will not be able to fix it without the schematics. I have no idea of where I can get them, can anyone help me??

I recommend trying to find a shop service manual for your car. Those are chock full of all kinds of info including schematics. I picked one up for my 92 for like $50 on eBay and it has been a Godsend.

All the wiring diags available. Your car is 1991, but the 1992 diags are all the same as the 1991 cars - nothing much at all changed in last 2 years of production.

Is your car TPI or TBI? You know that the IAC can also be cleaned, right?

Good luck! And welcome to TGO!

Oh - save this link in your favs - lots of great info here including those wiring diags: http://www.austinthirdgen.org/index.php?pid=2
