If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.

Idle control valve makes the idle high and with foot off the accelerator car runs at 40-45 MPH. I disconnected the electrical plug to the valve and car runs great!

when i start the car it revs up on and off with out me hitting the pedal. also it stalled twice on me while i was on the highway exit ramp. rear three spark plugs are impossible to get to and the driver side door wouldn't lock with the remote locking device or the car lock button.

Car starts,but dies immediatley when take foot off gas. When pressing on gas, will die if I dont rev engine. Also, this summer electric locks stopped working and recently car seems to idle high when sitting or when I put heat on.

Having this similar rough idle problem. Was going to try and replace the idle air bypass valve but the auto parts suggested trying a fuel additive BG-44K. Well had good/not so good results. BG-44K within 20-30 miles of adding it to a full tank stop the rough idle but the rough idle returned. I'm going to try another treatment before replace the bypass valve. Found BG-44K a lot cheaper on ebay, this stuff is not cheap but I'm a believer of it. So bigger maintenance question is do our fuel ejectors get plugged up from cheap gas / ethanol and such???
