SOURCE: Engine stalls while driving and sometimes while idling.

The stalling problem could be caused by a faulty mass airflow sensor. That is the PO100 code. The other code is for the engine coolant temperature sensor. Go to the autozone website at autozone .com and register your vehicle. It's free and you will have access to an online repair manual. The procedures for testing the MAF sensor is outlined there. Hope this helps and you find a resolution to your problem. Best wishes.

If the light was flashing when it came on, then it means your engine is misfiring.

A solid light can mean anything from a loose/faulty gas cap to a transmission issue.

This light comes on when the computer detects a fault of some sort in its diagnostic tests. If it keeps detecting this issue, the light will remain on. If the light turns off, then it has detected that the issue may no longer be present.

In order to find out what the exact reason was for your light, You need to have your car computer scanned to retrieve the code that the computer would have stored when the light triggered. Most garages will do this free of charge. The code will tell you what may have caused the light to initially turn on.
