I have a 2004 Impala SS With 38,000 miles. Last night I was at work and went to start my car and drive my half a mile home. It would not start, kept shtting down. Almost sounded like a lawn mower engine on slow idle then would shut down. As long as I gave it gas it would stay on, so I got halfway home when I had to stop to go around a corner it shut down so started again and applied gas all the way home.

This morning woke up and went to start it and it started no problem, but I called dealership where I have a warranty anyways to let them know. The service dept. said to put the key to the on position for 20 minutes to let the car recongize the key. I did so and after doing that same thing that was happenening last night happened again. The dealership is sending a tow to pick it up, does anyone have any ideas what might be causing it?

Thank You :banghead:

Many things can cause this, let them handle what ever the issue is.

Dealership called and told me they replaced the Mass Airflow Sensor, would that def. be causing issues I had?

Yes it could be.
