One more "help with my car thread"

[alm99]

I have a Saturn SL2 with 98K miles on it. Since friday every time I start the car, the RPMs go up to about 1,800 then suddenly just drop to 500 RPMs almost stalling, then it would level to 800 RPMs, its optimal level of idling, but today it actually stalled. I don't know what the problem is or what even could be. I haven't gotten the timing belt replaced yet, but will this week since its due. What could be the problem?

I had a problem similar to that with my car a long time ago. I can't remember exactly what the problem was but it was some kind of sensor or valve. It wasn't anything major.

Could be a TPS (Throttle positioner solonoid) Tells the computer in the car where to idle at.
