I am having a problem with my truck when i first go through the gears. It seems like it is missing unitill i go through the gears the first few times. Once i go through about three or four times it seems to even itself out and run fine. I have already changed the plugs, wires, cap, rotor, fuel filter, and also the air filter. I thought it might just be some bad gas or possibly the injectors so i have put some injector cleaner in the fuel tank but i still have had no relief. not sure what the problem is. I was wondering about the timing but i figured it would be doing it all the time if it was the tming. Also do you think it could be the fuel pump?

Not very likely. Does it smoke on start up? use any oil? coolant? could be bad valve seals oiling a plug or two overnight and causing it or a very small head gasket leak putting a small amount of water into the cylinder overnight

Im sorry to waste your time. I feel extremely stupid right now, after changing the plugs and wires i didnt think at that point to check the coil. When i pullled the air cleaner assembly off to attempt to check where i would test the fuel lines on the truck i noticed the the coil was discolored and had been arcking. sorry guys spark this one up to stupidity but thanks for the help anyways.
