01 takes spells of idling high

[aukster]

My van has recently took 2 spells of idling high. It starts while driving. I would pull up to a stop sign or something and would notice it would want to pull. When I would place it in park it would idle up to around 3000 rpms. once turning the van off and starting back it would be fine. I am curious as to what this may be. Also yesterday it took a spell of mising or something. I noticed it missing and looked at the tach and iot was jumping up and down. It did this for a few seconds and quit. Then later on it started again. I was able to pull off the road when it started and it died on me. I tried to start it back and could not get it started. Waited for a couple of minutes and tried again and it started fine. Any thoghts or suggetions on this? I am thinking it may be water in the fuel but I am not quite for sure on that. Thanks for the help.

You may be having an IAC (Idle Air Control) fault. If diagnosed as so, clean the throttle body too.

Another culprit could be a loose or broken TPS (Throttle Position Sensor).

Ignition problems may be involved but I'm not too sure.

Lets see what our resident techs have to say.
