I have an ’02 Chevy Impala with the 3.8L engine. While driving in ambient temperatures below about 40°F the engine will shut off entirely and I have to put it neutral and coast to the side of the road to get it started again, it doesn’t do it while the ambient temperature is above 45°F.
My routine before driving the vehicle when it is below 50°F ambient temperature is to start the car about 30 minutes before I leave work the engine temp on the gauge says its about 180° and by about 3/4 of the way home (10 mile drive so about 7 and a half miles) the temp gauge shows that the engine temperature is about 150° and it shuts off and I coast to the side of the road to start it then about half a mile down the road it repeats the issue again and continues to do so the rest of the way home.
I’ve already replace the alternator, battery, camshaft sensor, crankshaft sensor, engine coolant temperature sensor, mass airflow sensor, idle air control valve, and 2 of the 3 coil packs.
If anyone has any ideas on what the issue is please help I’m at my wits end.
