Check your idle air control valve(IAC), it should be along your throttle body. Try disconnecting the wire harness to the IAC and see if there is a difference to the engines idle. If there is no change it may be dirty with carbon build up and seized, it needs to be cleaned with throttle body cleaner or it may need to be replaced. Good luck and hope this helps. After cleaning or replacing the IAC you need to reset the base line for it's idle, Turn the ignition to the run position for 30 sec and then turn the key to the off position for 10 sec then start the ending and let idle for 1 min then go for a test drive. Good luck and hope this helps.

WOULD A IDLE CONTROL VALVE/IDLE AIR CONTROL BE CAUSING MY 2000 CADILLAC DEVILLE TO IDLE AT 1400 TO 1750 RPM SOMETIMES IT IDLES OK..IS IT A HARD FIX..THANKS...


Try cleaning the throttle plate first . I wouldn't just change the IAC valve without testing , hooking up a scan tool that show engine data.
A few different thing's could cause high idle .The idea is to test all thing's that could cause a high idle till you find the problem. Vacuum leaks , throttle plate sticking because it's gummed up with carbon , varnish build up . Or is the PCM/ECM making it idle that hight etc... Is the throttle cable bound up.

I would check the throttle body, where the fuel mixes with the air also clean all pipes/connections etc after that you should know where to go next, but give the "plate" inside where fuel and air mixes, carb

My 02 3.1L V6 chevrolet malibu one day started to idle at a higher rpm than it normally did. It happened at around 72XXX and now is just acting funny. i kinda have a clue what it could be but does anyone...


Most likely it is a vacuum leak some where if you have a propane torch do not light it but let the gas flow out slowly as you move it around the engine and if it revs up you have found you leak.

2000 chev malibu is reading a po420


po420--- catalist efficiency below threshold--- possible fix. a po420 means that one or more of the following has happened. the easiest thing to do, is erase code with scanner. and see if it comes back. the engine coolant tempuature sensor may not be working properly, damaged exhaust manifold, or catalytic convertor may be bad. check 02 sensor also behind convertor towards rear. its really hard to say can be anyone off above!! but check 02 sensor first it may be bad.

99 malibu always read inconsistant fuel levels but now engine light came on and stalled on the highway.Codes read lean fuel and misfire. Exhaust smells horrible she sputters when left idle and idles low...


check to make sure catylitic convertor is not plugged. if it is ok, then put a code scanner on to read codes, may have a bad 02 sensor. if you dont have a scanner, most auto parts places will scan vehicles for free.

I have a 02 malibu that keeps dying out on me while driving and idealing. New starter put in and still does it.Had a shop looking at it for 3 days and still nothing.Please help!!!!


Faulty idle control valve. Fuel filter clogged. Damaged or wet ignition system wires or components. Faulty idle contol sensor. Spark plug wires. Vacuum leak at intake manifold or vacuum hoses.
I know a guy whose Blazer was doing the same thing. All it was, is a broken vacuum hose on top of the engine. He had been to the dealership 3 times, and i fixed it in 15 seconds.
