I have a 2001 Lightning, it has a JLP built motor, stage 3 cams, motoblue 2.75upper pulley, predator programmer, and I really don't know what the lower pulley is. Anyways, it had would bog down when you would get in the boost and I thought it needed plugs so I put plugs in it, TR6s, it had Denso IT24s in it, well turns out that it had water in the gas. So, we dropped the gas tank, got all the gas out, changed the fuel filter, and i drove it down the road and it ran fine for like 7 seconds, then it just developed a dead skip. Before, the bogdown/skip was only when you would get in the boost and now it it is all the time. The only CEL i have it an o2 sensor. I don't want to throw a bunch of parts at it that it doesn't need and I don't want to do anything to hurt the motor. The truck REALLY needs be tuned but I need to get the skip fixed before I put it on the dyno.
