    3.8 motor you can drive for about 5miles then the tach starts Jumping around and the car will shut off if you don't keep your foot on the gas but it feels like its only running on 3 cyl. If you let it sit for 10 min it will run fine seems like it only does it on the highway though can anyone help me?

    Is the CEL on? If so, get it scanned and give us the codes.

    Other than that the crankshaft position sensor sounds suspect. Also could be a bad ICM or MAF.
