2001 trooper. 3.5L, auto. When running, runs rough. But now, it starts up, revs up, then dies!?! At a loss!! Pls help
Thank you, I will try that.Symptom of a few things.. however MAF sensor is normally the fault. to test the MAF simply unplug it & start the engine. Will will be harder to start but it will start and level out. If the problem continues afterwards then, the MAF sensor is fine. Id the problem goes away then the MAF is dirty or faulty.
