engine skip/lugging help

If it was a plug wire it should be running rougher at idle. You can let the truck idle and pull one plug wire at a time from the cap and see if the idle gets rougher. If it does, then that wire was working, if it does nothing, then that wire was the problem.

Have you touched the timing or any vacuum hoses?

havent touched the timing its at 6 degrees advanced. i removed the smog stuff when i did the exhaust system and put the headers on, so i had to cap some vacuum lines. its possible that some of the plastic ones cracked cuz i broke one and had to fix it...
