I would consider changing the vehicle speed sensor. When they go bad, they can really throw out a lot of bad data to the computer, resulting in unexpected behavior like you're experiencing. They're only around $20-$25. I hope this helps! :)

Idle problem on v6 ba astina hunts from 1000/1500 revs


Engine stall or RPM fluctuates at idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

Hi, I have a 1999 Chico/Citi Golf. The revs stay above 1000 and do not want to drop, I do not even have to pull the choke out. How do I get my revs to drop back to 1000? It use to Idle just below 1000,...


Check that the choke accelerated idle cam is not stuck. Check that the throttle cable has not dislodged and the outer casing is riding on the bracket. Check that the throttle linkages are free and the throttle returns to the idle adjustment stop. If all these are correct, adjust the idle adjustment to obtain the correct idle speed. 700 - 800 rpm is about the right speed.

When in park honda odyssey revs up and down between 1000 and 2000 RPMs


is the check engine light on also? it sounds like the idle air control valve is bad. this controls the idle of the vehicle. when it is stuck open it causes too much air into the engine and causes it to rev. when it gets to a set rpm, the pcm cuts fuel. then it turns the fuel back on, then the engine revs, then it cuts fuel........code p0505 will prob be set

Engine high rev at stop and slowly goes to idle speed.


I've got Hyundai Lantra 1.6 year 2000. It's take time to start when it's hot. When I start my car it revs at about 2k-3k rpm. It also does it when I come to a stop. When I come to a stop it will stay at a higher rpm than that of idle speed. It drives ok when on freeway but uses more petrol. I have changed the water & petrol pump but no luck
