idle very high, help.
my car starts up at 2500rpm..than goes back down to about 1500, which is still very high, and when i put it in drive it will idle at 900-1100....my car will basically drive itself to about 40. my car only runs good when i have the bottom two 02 sensors unplugged. if they are plugged in, it will run very rich. from what ive noticed, it seems like my car is getting too much oxygen...but idk. help me please.
thank you
Evan
or do you mean submerged in water? That woudnt be good but if it got rained on I dont think that would be a big deal. There is a way to test to see if your pcm is bad. Turn the car on and let it idle. Gently yet firmly tap the pcm with a screwdriver if the car idle surges it usually means a bad pcm. but if not, what do you think is the next thing i should look at? it wasnn't submerged under water, but it did have water in it, and when i turned it upside down and shook it, a bit of water dripped out of it.
