I am having a problem with my car stalling out while driving. Sometimes my car runs fine with or w/out my A/C on. If I leave my car running it will eventually stall out while sitting still or when I slow down to make a turn. I changed my plugs last year and I put a new fuel filter on at the same time. Any help would be greatly appreciated.

 

Your alternator is dead or dying.
Heres's a quick test to determined if its the alternator or not.
Start the car and leave it on. Go to the battery and disconnect the Negative terminal only. If the car doesn't die then its not your alternator, but if the car dies right away then its the alternator.

 

with the 4th gens you can't do that just take it to autozone have them run a test on your altenator to see if it is dying i had the same thing happen to me a few years ago luckly i was still under warrenty

 

I just had a new alternator put on my car back in February. I'll have it checked out though.
