    Spark, fuel, injector pulse or compression! Which is not there on the cylinder(s) the power control module says has a misfire? Then may be able to help. Coil pack can fail at any one or more plug wire terminals!!!

    Wouldnt this show up as a code? The van has a miss that drops around 1000 rpm most of the time but not all the time. Nothing showed up on the mechanics code reader except it always goes back to a bad cam or crank sensor.
