After checking everything about 3 times the only thing I can think of is that it skipped a tooth but I still don't see how so Im going to pull the waterpump housing this weekend and make sure. This sucks ***!!! :cussing: :cussing:
Was the timing chain set new? If so, it's not likely at all that you've jumped. I've seen high mileage motors with timing chains "flopping" that had not jumped. Still sounds more like a plug or plug wire by it not being a constant miss or "dead cylinder". Visually check all plugs for cracks and all plug wires for any defects paying close attention to the boots. Good luck.
