Is it definately getting fuel up there? thinking maybe ya fuel filter might be blocked, doubtful but hey
Some things to try bro,
plugs, check cond. and gap
leads, just use a generic one and try swapping them out 1 by 1, that way if it is missing on 1 cylinder you can determine which one it is at the same time
Lastly maybe swap a coil out 1 at a time, also just go flog a tr unit off a magna at the wreckers to try, hopefully ya dont get a dud
