I have a 2001 Rodeo. A few days ago the service engine light came on for a few hours, then off. When starting up from a stopped position the rear wheels skip and spinlike the car is trying to peel out. After it shifts into second it stops. Also after the first one or two stops the spininng stops altogether. Let it sit for a few hours then the problem starts again. The mechanic didn't get a clear indication from the computer trouble code. The spinning seems more frequent but there is still no check engine light again. The mechanic is thinking it may be an idle sensor but that is just his guess.
