Problem overview

Some Pontiac G3 owners report experiencing fuel smells and stalling issues that cause the car to thrust forward repeatedly. These problems may stem from various factors, including fuel system issues such as a failing fuel pump, severe fuel leaks, or obstructions within the fuel system. Additionally, a damaged gas cap or faulty valve could exacerbate fuel-related concerns. Some owners also find that erroneous signals from the Mass Air Flow (MAF) sensor can trigger the check engine light and contribute to stalling. Furthermore, problems within the ignition system may lead to similar stalling issues. It is advised that owners have their vehicles inspected by a qualified mechanic to accurately diagnose and rectify these issues, as prompt resolution is essential for the vehicle's safety and proper functioning.
