1993 Pontiac Grand Prix 6 cyl Automatic 150000 miles
I have a 93 Grand Prix 3.1 that was running great, then out of no where it started running ruff mid trip and died. I have replaced the fuel pump relay. I was told to replace the ECM relay, but after purchasing it, I can not find where it goes. I replaced the fuel filter. The car starts fine and runs fine in Park, even if I give it gas, the engine revs up fine. Once I put it in Drive it starts to chug and when I give it gas and start to go, it dies. Any ideas?
