can check it, but would be good to know if unplugging the IAC changes the idle. It could be stuck partly open, or there might be a leak around it. if the idle drops and/or it stalls, the ECM is holding it open for some reason. Basically isolating it to a hardware vs controls problem.

Thank you Gadget.
With the engine warm I disconnected the IAC with the car running. The idle dropped to what i guess is normal. 700-750 rpms in park and around 600 rpms in drive. It did not stall out.
I then drove around the block which is about a mile.
Will it hurt anything to drive with it disconnected? I THANK YOU again.
Should be about 500 at idle with that unplugged.
How big is the air bleed hole in the throttle body?
its probably not going to be happy with the IAC unplugged.

You're right. The IAC was not happy unplugged on a cold start this morning.
The throttle body has been on since May of last year.
I'll check and see if the PCV hose came loose again. It did come loose from under the middle of the intake when I replaced the relays and the fuel filter. If it's still a high idle
I will probably go back to the previous IAC.
THANK YOU.
