i need an experts help. i have a 1994 honda accord automatic transmission. when i start my car in the morning the car idles up to 2000 rpm then goes down to around 1000 rpm or so. i drive the car 20 or 30 miles everything is fine on accelleration no misses at all, temps r good. idles fine in drive forward and reverse but when the car is put into park the idle hunts for itself. thats is it revs up and down until i turn of the car. i can start the car immediately and the idle is fine. does anyone know what this is? is it the IAC? thanks in advance.

 

iacv

 

maybe fitv

 

Clean out your IACV and adjust your FITV back down. The FITV is what controls your idle at cold start up til its warm then thats when the IACV comes to play.
