after using cruise control the car will idle at about 2000 rpm for a few days then return to normal, i replaced the trottle position sensor no change any help would be great
Tps?
It almost sounds like the cable from the cruise servo is binding, and in turn, holding the throttle blade open a small amount.
It's easier to eliminate the other variables. You've already replaced the TPS, so why not remove and clean the IAC valve. They tend to get carbon build-up and have negative effects on the idle quality. If that checks out, you can look into the cruise servo and/or its cable to the throttle body.
clean the IAC made a huge difference in my car somtimes it would idle fine and then it would idle at 1400. make sure you buy a new gasket because i tryed reusing mine with some rtv didnt work that well. when i cleaned mine i took it off and let it soak in a gallon can of carb cleaner and then cleaned it more with a spray can then put it back on and it makde a world of difference.
also take the intake tube off and start the car and shoot some throttle body cleaner in that too at the very top of the throttle body i found alot of junk
pull your codes with a paper clip.
you can also pop the cruise cable off the throttle body and see if the cable slipps easy in and out.
