Default 93 bird
My 93 bird is misfiring. Did plugs wires fuel and air filters. Any ideas?

The optispark is essentially your distributor. When they get fouled up, you get misfires like crazy. Replace yours with a vented 95-97 style and it helps the longevity. Do a search and you'll find more info than you can shake a stick at.

Was it misfiring before the plugs and wires ? if not recheck all your wires are installed correct

Go over it and make sure everything is plugged back in correct , did you take it off an put it back correct ? When you took it apart did you use locktite to put the screws back ?

Would NOT using the locktite keep it from starting? Everything else seems to be in it's place and secure. Could I have messed up the time?
