Pontiac Sunbird ProblemsThe Engine May Stall After Extended Freeway Driving
The torque converter clutch can stick "on" after extended freeway driving causing the engine to stall when coming to a stop. Our technicians tell us when this occurs, the engine usually will restart and stall when put into gear. After allowing about twenty minutes for the engine and transmission to cool down, the engine will start and the transmission will operate normally. Replacing the torque converter clutch solenoid, transmission filter, and fluid will generally correct this issue.
The ignition module or crankshaft position sensor may fail causing the engine to die and not restart. Diagnoses will be necessary to determine if the module or crank sensor is causing the no start condition.
A dirty throttle body may cause a lower than normal engine idle resulting in a stalling condition. A stalling condition may also result if an idle learn procedure is not performed if the battery goes dead or is disconnected.
