    Default 2003 w/ 5.3 quitting at low RPM

    I have a 2003 chevy silverado with a 5.3 liter V8. it has 101,000 miles on it. All of the sudden, when I am stopped at a stop light, and the RPM's drop below 1,000. The motor will sputter and then quit. It will also do it sometimes while driving if under 1,000 RPM's. i have no idea what is going on. please help1

    Default Mass Air Flow sensor

    Could this issue possibly be a mass air flow sensor?

    Default

    It could be my friend had a bad mass air flow sensor and his mustang would sputter untill like 2500 rpms, all was solved when he replaced it. Not sure just an idea.
