Problem: Went to work one day car ran great go to leave the car has a hard time starting then just dies It throws a CEL and the TEMP light. I left it over night, came back to pull it in the shop. Runs fine. Change the fuel filter, same problem. Let it sit for 15 min starts alittle hard then runs great. Warmed it up to temp took it down the parking lot full throttle to complete stop fine. Come back an hour later wont start turns over wont start. I changed the spark plugs and wires. Still wont run and throws a Check Engine Light and temp light. I have spark at the coil packs, spark at the spark plugs, fuel pressure to the fuel rail and fuel to the spark plugs. Its almost as if the timing is off. Shes wants to start and if you feather the gas it will run VERY rough and blow black smoke out. WHAT IS WRONG?
Questions : What could it be and can I retrieve the CEL like the old GMs by using a jumper in the diag plug?
have the same problem?
