Could this be a battery or alternator problem? Or is this bigger? Guest Anonymous Poster Mar 17, 2009, 3:08 PM Post #2 of 5 (1734 views) Re: when ac is on car dies Sign In This is a 2003 Ford Taurus.

The engine has an IAC (idle air control) motor that is supposed to compensate for that drag by raising the idle speed. Assuming that there isn't a problem with the compressor, the IAC may just need cleaning. Have you had an injector cleaning service done, yet? Recommend every 30-40,000 miles.

I just bought the car in December so not sure that has been done.
