This truck is gonna break me soon I think. I've just recently changed my plugs, wires, and ignition coil. But when I put the timing light on it just see when it fires, it will fire consistantly on 3 of 6 plugs. Then the other 3 will fire consistantly but then skip out then fire more then skip out. It's causing the truck to jerk trying to keep it at 40 in 4th gear. Misses while it idles now and misses while accerating. Huge gas consumption right now. What else could it be? the timing light is proving the firing isn't right that it couldn't be a pump or injectors.
