P1391
 
I have a 1997 Jeep Wrangle Sport (4.0 inline 6) that is throwing a code of P1391 (Manufacture Ignition System or misfire). I have already replaced the Crank Sensor and Cam sensor (distributor pickup). I am not sure what to do, I have read about some people replacing the whole distributer. Any ideas?

Check the connections between the sensors and the wiring harness. They get dirty, wear and get loose creating the intermittent signal.
