IAC
my car is it hanging aroung 1500 rpm's (for 10-30 secs. ) when i let off the gas ....i have cleaned the the throttle body, IAC and TPS .....and the cable springs beneath the throttle body
....i dont have this problem if i unplug the IAC...it seems to run better and more responsive..
...are these signs of a bad IAC?
...whats wrong with leaving its unpluged?

RE: IAC
It's most likely an IAC issue. Have you tried cleaning your MAF sensor also? I have found that when my MAF gets dirty it creates all sorts of wierd running issues. Once I spray it down with some carb cleaner all of my issues go away and it runs like a champ! Also check your PM's.

RE: IAC
first take your IAC off and clean it, then if that doesnt help try sending Streetracer911 a message or look for his thread on a block off plat.

RE: IAC
I agree with scanning the computer, see what realy the problem is for sure, I mean at least you wont be guessing. Leaving the IAC wont hurt nothing, just the the TB slamd shut, engine might stall/die, and when you stopped you might have problems.
Hell, Adder did that for a while, dont think it was too big of a problems for him.

RE: IAC
I had the same problem...I tell you what fixed it..it may sound stupid, but I got thinking how other peoples car would stall when you unplug the IAC, mine didn't, so I unplugged my IAC, turned down the idle screw till it stalled. Then Iplugged it back in and checked to see if it would idle, unplugged it to see if it would stall then resetTPS. That fixed it,I had my idle settoo high.

RE: IAC
Mine doesnt stall, but its idles at like 1100-1200, and when i turn the idleas screw, the idla quality sucks real bad, So i think i might do what you said, and i would gonna look at the tps reading tomorrow, since ive messed witht eh screw lately and didnt think of check the tps voltage.
Hope thinks might help some
