Posted: March 24th, 2012, 12:16 pm
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.
