Idling problem need help
Idling problem need help I have a high idle that started while I was moving this car last winter from one garage to the other. It doesn't throw any codes, but idles at 1500 rpm or so whether it's in open or closed loop. I looked at the datalog and TPS looks good, but my IAC is a little higher than it should be. Anyone willing to take a look at it for me to offer some assistance?
It's been a while since I've looked at datalogs or tuned so any help would be appreciated. Just send me a PM with your email so I can send you the Datamaster file.

Changed IAC and that didn't help. Exact same problem. I looked for vacuum leaks and can't find any anywhere.
TPS sensor is good. IAC reads higher than it should, but that's because the idle is high. About the only thing I haven't done is adjust the TB blade screw, and the reason I haven't is because I have never messed with it before. It idled fine where it was supposed to, and then all of a sudden on a startup on a winter day it started idling high and won't drop back down.
I really need help, are you kidding 28 views and no replies. Please people give me some advice.

i couldnt help you with looking at your datalog, but i would def say dont bother with the TB screw..i honestly dont even know why its there..you're supposed to adjust your idle speed through tuning..not the screw...i have two suggestions...check ur o2s on your log and make sure its not something stupid...like your accelerator sticking or something...stick your toe under the pedal and lift to see
what i was going to say. the plastic clips on mine broke once and caused my car to idle high. there wasn't enough tension on the throttle cable to completely help the return spring close the tb all the way
