Just had mine done on my Express van, has the 4.8. Was misfiring on cyls 1 2 5 6 and 8. I checked the old gaskets and didn't see anything obvious either. Van had a constant p0300 since I've had it.Mechanic thought so. I was on the fence with the smoke machine. But he seemed sure. So I did them. Should be able to tell tonight if the bank 1&2 codes are gone. In addition ill re scan and send logs .Its too icy tonight for hot laps.
