Did you check for vacuum leaks? Get a can of some flammable brake cleaner and start spraying it near all of the vacuum lines and see if it idles down. Also spray it around the intake when you hit the right spot it should idle down. Then you know where your problem is.

    The IAC (intake air sensor) controls idle speed. It screws into the side of the throttle body and has two wires attached to it. Check if it is getting power to the unit the car should be running, or disconnect the unit and see if idle speeds up more. The unit is easy to replace, and instructions are included on how to adjust the pintel for the right initial idle speed,

You need to clean the IAC again and also the throttle valve and bore, use only CRC brand Throttle body cleaner. After they are thoroughly cleaned disconnect the battery for 5 min's and then drive the car in varying condition for a few days. If that doesn't cure the issue you have more serious problems and will need a scan tool to look into the readings from the MAF, TPS and ECT sensors. High idle cold start is normal then slowly dropping after a few minutes. I assume you never had a check engine light. Correct?

My experience has been with later model vehicles, but a bad throttle position sensor most definetly causes this type of situation. Two torx screws, opposite side if the throttle body, should have a three wire plug.

My 2002 dodge durango hits 4000 RPMs and bounces between 3000 and 4000 RPMs when I am in park and have the throttle held down. I replaced the cam sensor and it is still doing it.


this is your rev limiter stopping you from over reving engine causing internal damage. this is normal on all new vehicles. Don't know what year they started this but it goes back at least 16 yrs

try disconnecting the battery for 5 minutes or so, press the brake pedal with the battery disconnected. after 5 minutes reconnect the battery and start the car, DO NOT TOUCH THE THROTTLE/ gas pedal for about 5 minutes. perhaps this will recalibrate the computer. good luck, hope this helps

200 Pontiac Grand Am over 3500 RPM loss of power


on almost all gm cars after 96 the engines were governed to not free rev over 4000rpm. when in gear and power braking the rpms stay lower cause of the load on engine. when reving above 3500 rpms the computer cuts back the timing and fuel to reduce engine damage if left to free rev. hop that helps.

94 honda del sol's engine revs up and down


I know exactly what you are talking about, it will go high to about 2 to 4k rpms, then back down to 1k in intervals of about 3 seconds. It is either the idle air position sensor, or the throttle body position sensor, hondas are famous for it. The parts are cheap, about $20-$30, and fairly easy to install when you find it. I suggest a Haynes Manual for installation to make it a lot easier if you don't know where it is. Good luck, hope all goes well.
