need some help on a 81 280Z 5-speed 2.8 missing in gears 1-3 on 1990 Nissan 240SX

when you accelerate from start it miss in gears 1,2,3 after that it's OK what could be causing that to happen

its most likely missing in all gears but u just don't feel it unless your under heavy load. look for plug wires shorting out or bad plugs to start with. you can mist the wires lightly with water and poss see them arching to grounds inside a garage.
