I cleaned the IAC too, looked like fresh oil on it, Maybe the engine has excessive blowby... It ran good for 2 min of driving then ran like crap.. Runs great with the IAC disconnected..

89 Gt
E303 cam (I think)
Sub-frame connectors
I think it has a port job
Might be re-geared
Set up for nitrous (police removed it)
Give me a break, it was from an impound lot, It's quick that is all I know.

OK, this is an old thread, but now I have considered selling my stang. TPS voltage is correct, now I have bypassed wires in the "salt and pepper shaker" that send signals to the pcm from the tps, I found a bad connection in there (you can wiggle the connections behind the intake and it would lose connection). So, connections are good, now I have bypassed the IAC wire in the middle of the white connector (B/W wire). But it will run fine, then stick at 1500 rpm.... I need opinions. Do you guys think the IAC is sticking? It is sluggish when shifting (rpms stick). Thanks a ton in advance. I must add, the exhaust seems very rich and is almost unbearable to drive. And it does not have the power it should (tons of low end, but loses mid-upper hp). also has new 02 sensors.
