I have a 93 lumina and when I start the car its idle high then shuts off for no appaernt reason. Then I try and start it again but it wants to turn off so I would have to give it some gas and put it in drive really fast just to take off. When its in drive its jus fine. But the fan comes on like every 15-20 min what could be the problem....anyone?

SOURCE: Stalling

The break cylinder in your engine goes into a item that looks like a pie. it is a big cylinder. This controls vacuum in and out. The reason it stalls is because this item is bad. I had the same issue and my son and I reoplaced it and all is well. So from the master cylinder it connects to this item. I apologize I forgot the name of it.
I would highly suggest you take it out and take it with you to the autoparts if you intend to DIY. The reason being is that depending on what month your care was made the main piston that attaches to your break pedal from there comes in two different sizes and I learned the hard way that this is the case...
Hope this helps.

Two items to look at: Throttle position sensor, $45-50. PCV valve, $4-5. Either will, at times, produce problems with idling.

Could be either one of these. Or both. Check to see if you hear the fuel pump when you turn the key to ON. If you can't hear anything , the pump is bad . Or going bad if you don't hear it all the time when your key bis in the ON position.

Most auto parts stores will scan your on-board computer to see if there are any error codes stored there. Call them first; this service is normally free. That may tell you if a particular sensor or device is or has failed.
