Uneven idle after cleaning engine

hyatt200 · 12-06-2006, 06:30 AM

i done the same thing. the motor looks great now ,but once warm, the idle goes up and down. i took it to the dealership. they told me my TPS was o.k. My MAP sensor was o.k. they said my idle speed control valve was not functioning properly and wanted to replace it for $478. i brought the car home and will check it out myself before looking for one.

before taking it there, i found that i flooded the area between the cam covers where the plugs are. fixed that. distributer was wet. fixed that. changed plugs , wires , distrib cap , rotor etc. drove it for days on end. finally gave up.

a haynes manually tells you how to test each sensor. you'll need a meter for that. mine's a Fluke brand meter. very time consuming.

hope this helps. no one ever answered me when i posted the same question. heck , i cant even find my posted thread. nice to see i'm not the only clean motor freak.
