Pontiac Bonneville repeatedly dies at red lights and turns on Pontiac Bonneville

Some Pontiac Bonneville owners report experiencing issues with their vehicles repeatedly dying at red lights and turns, which may stem from several potential causes. These owners have noted that the engine sometimes gives two clicks and dies intermittently at low speeds, indicating possible problems with the electrical or fuel delivery systems. Additionally, some models feature an automatic engine shutdown at stoplights designed to save fuel; if this feature malfunctions, it could lead to stalling. Other owners have encountered situations where the engine dies suddenly while driving, restarts briefly, and then dies again, suggesting issues with the battery, alternator, or fuel pump. Stalling can also occur when using the automatic window switch, pointing to possible electrical problems. Furthermore, if the engine dies when fuel pressure drops, it may indicate a failing fuel pump or filter. Owners have also found that unplugging the Mass Air Flow (MAF) sensor can aid in diagnosing stalling issues, and persistent problems could be linked to the crankshaft position sensor. It is recommended that affected owners consult a qualified mechanic to diagnose and resolve these issues, ensuring regular maintenance to prevent future stalling incidents.
