Twice in 1 week my car has stalled, once when I was turning into a driveway, and the next time when I was stopped at a light, both very bust area, really starting to panic, just perchased the vehicle 2 months ago, has 48k miles, Not sure what to do next? What could it be? Could it be the air intake valve? Please HELP!

Almost every single time I try to stop the car shuts off, it all started a little while back and I can't quite figure out what may be this issue. Also when it rains I end up having problems with my stereo. The sound will not come out every speaker.

Scan for codes and check fuel pressure with a gauge first. Have radio guy check for water intrusion clean throttle plate with choke cleaner on both sides.

When I was driving yesterday. When I came to a stop the car wanted to die so I had to feather the gas to keep it running.

Try choke cleaner on both sides of the throttle plate and clean the gunk off of it, that causes the problem you have alot of times.
