What could the problem be? It's only every once in a while that when idling or in gear at a stop it will stumble and drop rpms <500. It has always come back up, but tonight it died in the driveway when I put it in park. All I had on the A/C & the Xenon's. Could it be the battery or the alternator or maybe something else?

 

Look at the battery's "eye" and make sure its green (charged) and not black.

 

What kind of mods do you have? stereo, pulley, etc? I don't think the battery was the cause of the problem.

 

Battery is green, but I remember another thread where someone's battery was dead and it still showed green.

 

If it wasn't the battery, then you may have a defective alternator. This could be caused by the pulleys, or just a bad apple out of the bunch. Get it towed to the dealership ASAP...A $30K car shouldn't die like that...Especially a 2001.

 

If you have pulleys, get a stronger alternator and a better battery. If you don't maybe your battery needs to be replaced or your alternator.

Try taken it out of drive when you hit the back wall of the garage and it wont stall

 

it happened on my last car like that. i had a civic with cai and somehow the idle "changed" and wouldn't be able to keep up with the car when it was at idle. i reset it to the factory idle rpm and that fixed it.
