I cant figure this one out...
On start up, I shoot up to 2k rpms for a second and then creep down to about 1200rpm. In gear, i sit right around 1k rpms. I have played around with my target idle and it has made no difference. I checked for a vac leak and have found nothing. Unplugged the maf and again... no change. Just wanna see where to go next here as far as figuring it out (pcv/IAC maybe?) before just throwing money at it. Other than this the car runs fine it is just annoying.

What does your tps read at idle?

IAC is a good place to start, but what bill said ^ first.

Anything over ...oh wait.. what year? Because DBW uses throttle plate for idle

tbs is at 0 and the IAC is at 185 (which I think is a little high). Car is an 02 but I have a LS1 TB setup.

If the IAC moves at all chances are it probably works make sure it doesn't stay at 185 all the time or u need a new iac. You said u checked for vac leak did u use carb cleaner? Or eyes? Lim, t fitting under sc snout, tb gasket, vac going to your map sensor are main places to look also what is your map reading
