remove the hypertech chip and toss it in the garbage, install autolite 25's (copper core) and bump your timing to 12° base

autolite 25's.......you could narrow down the misfire with a koer cylinder/power balance test, this will locate a cylinder that is not contributing power wise if misfire is severe enough.

try the tune up stuff first, = cheap and easy expecially if it hasn't had one in a while
