Hello I have 1998 Jeep Cherokee Sport 4.7L Stroker That I keep getting a P1391 Trouble code. I have replaced the Crank Position Sensor, Re Indexed the Distributor same results. The Engine starts up and runs fine just keeps setting this code and preventing me from getting an emissions test. Any Help will be greatly appreciated.

Please do not post the same question over and over again on the forum. That is considered spam, and warrants a ban. You have been warned.

As far as an answer to your question, i do not know.. maybe someone else will chime in. Check your grouns? Maybe the flywheel your using has some issues?
