The check engine light means exactly that=CHECK ENGINE. Have your car scanned and get a pritout of the DTC's. Correct/fix all problems reported. Clear the CE light and drive. It will not show up until you have another problem.

You will need to have your car's ECM (Computer) read by a OBD II scanner to determine what Trouble Code your ECM is giving so a mechanic can properly diagnose the problem. You can go to your local AutoZone store and they can pull the codes out of your ECM for no charge.
Hi, this sounds like a voltage issue to me. Did all the lights go out on the dash, including the check engine light. Your best bet is to get the fault codes read at a local garage (not the main dealer unless you have money to burn). They should be able to give you indication of what caused the light to come on and you can take it from there.
Don't know if it is any help but I had the same problem and it turned out to be the intercooler hose was split and sucking air. Fixed it and know problem now.
I had a similar problem with my Saab, stalled at red lights when idling,
As suggested by Greg I suspected the IAC and was just about going to the repair shop and have the ECU codes pulled.
Anyway, I decided it could be a good idea to check the engine air filter first. It turned out to be rather dirty so I changed it, This solved the problem in my case, the car has worked perfectly ever since.
