It's a 97 TJ with a 2.5. Every time I start it up it will rev up to around 1800 RPM for a few seconds that come back down to under 1k. When I take off when it is cold and start to hit the gas it will idle up again. If I come up to a set of lights and push the clutch in, it will idle high until I stop then idle down.. After it warms up it goes away.. BUT if I pull up to a store and turn it off, run in for a minute or 2 and start it up it revs up again.. Then goes away.
I changed the TPS and IAC sensors.. Cleaned the TB as well really well..
I'm stuck!!! I never did this when I first got it...
ANy other suggestions?? Thanks everyone!!!
