I start my car and from time to time, NOT every time... prob 50% of the time it will rev to 2k rpm then drop to a little bit under 1k

I had a tune up done, that didnt really take care of it, it happens less now, but still happens

One shop told me it sounds like a SENSOR problem

Haha I was just about to say that. It idles a bit high when the engine is still cold.

not that high. it could be the TPS. mine was doin that, and i replaced it from another TB i had and it stopped doin it.

take it off and reset the ECU and see if it still does that before replacing it

does it surge?? like rev up and then down?

it's a common thing among our tegs... search "surging idle" and we have a bunch of threads about it and what some of us have done to fix it...

other than that, i'd say, wait til winter, it'll do it then too, i think it's just your teg warming up...

yea its common but now that i remember, mine surged. i cleaned the IACV and replaced TPS and it stopped.
