    If its missfiring what cylinder is it at? Have you checked the distributer and rotor to make sure they were reinstalled at the correct poistion. Do you have all the wires going to the correct cylinders?

    Replace the ignition coil, it's like $40 for a performance one, and are you using Platinum plugs? If you're using copper top it'll melt those things and can cause a miss.

    When you say "furthest", do you mean furthest from the distributor? #1 and #2 are at the front of the engine.

    Are you saying using copper plugs in this truck will cause them to melt?
