My 2001 chev cavalier is revving around 4000 rpm and the throttle is not stuck,any ideas
check for vacuum leaks. also, it could be your IAC or TPS sensors that are attached to the throttle body.
it might help if you filled your registry out a little more.

thanks for the info,strangest thing I was driving down the highway coming into a small town let go of the gas and the car just kept on traveling at the same speed.I thought throttle body was stuck but its not.If I start it it revs to 2000 rpm and slowly works it way up to 4500 to 5000 rpm,very strange.No problems at all except for somtimes when accelerating when its cold it somtimes "bucks" a bit.Any more Ideas would be greatly appreciated
any check engine light on?
It's more than likely your IAC. Either use throttle body cleaner to clean it (remove it first) or replace it.
God bless America.
help i still can't fix this problem.car has been in a garage for 3 days now with no fix.Tey changed the iac valve map sensor tps sensor removed emc and had the programming checked but car still idles at 4000 rpm.Also no vaccumm leaks at all help ........
couple things to check
1. as the car is idling, spray some carb cleaner around the intake manifold and injectors. it's possible that you have a leak around one of those. if there is, when the motor sucks it up, it should bog down a little and the idle will drop. if that does happen, replace your intake mani gasket and injector o-rings.
2. disconnect your battery for about 10-15 minutes. hook them back up and see if that helps.

They did check for leaks around intake manifold,no leaks.I tried dissconnecting battery for half hour still same problem.Does any body thing it could be a bad ground,has anyone heard of this before?
no you have a vacuum leak, try unplugging your IAC see if that does anything
Where would be the most common place for a vaccum leak?Brake booster
