I am getting a really bad miss on my 87 hardbody. I have changed the plugs, wires, cap and rotor. Any one have any idea as to what else it could be?

Pardon my ignorance on your particular year - but is that truck fuel injected or carbureted?

Are the injectors separated to individual cylinders (e.g. one injector feeds 1&2, and another one feeds 3&4)? If that's the case, I'd check to see if you have a clogged or failed injector. Today's ethanol "enriched" fuel plays hell with the older injectors...
