sounds like a timing issue...loosen the distrubutor hold down bolt.... start the truck and then turn the distributor until it smoothes out.... mark where the distributor was when you started.

2 out of 2 people think this is helpful.

The timing may be a little off . There are two opposing cylinders not changing the sound of the enging while running. cyl. 3 and 4 no change at all when plup wire are pulled good compression and spark I will try your suggestion Thanks

I tried rotating distributer no change in misfire
