View Full Version : Idling High

I just noticed my TB idling high for the firs ttime today.


I pulled off the freeway to get gas (after traveling 150 miles or so)... and I noticed it was hard to brake/quick to go. Naturally first thing I looked at was the idle rev...

It was around 1050 rpm, normally at 650rpm... I pop it in neutral and it remains at 1050...

Being a computer person I assumed all would be good after I turned the car off then back on. No go.



Whats going on?
