so heres my problem, i took my car for a long trip (philly to pittsburgh) over 400 miles. Ran beautifully the whole way until i hit stop and go traffic and noticed that i was idleing at 1500 rpm. after my trip i let the car sit and messed around w/ the TAS but it wouldn't drop any lower than 1500 . I figured it wasn't a major problem so i left it alone until my return trip. On my return trip i put it in neutral occasionally to check my rpm's. and heres where it gets weird. the rmp's would get stuck at 2000 until i blip the pedal, which then would go back to 1500. This is now happening often (but not always). What should i do? would adjusting the AAS help w/ this? Why is it getting stuck at 2000? Thanks for all your help ahead of time

check the idle while you are completely stopped.........



usually when the car is moving the idle wont settle all the way down

vacuum leak?

are these symtoms of a vaccum leak?

yeah.. high constant idle usually is a vacuum leak.... but its only one possible answer of the myriad of the things that could be wrong.
