[johl]

Mine would run like this when a lead was loose on a plug. Would just spray some contact cleaner and she would go back to normal.

exhaust leak and bad tune?

[haveaparty]

Yeah man got a loose lead or its not connecting proper. So ur only running on 3 cylinders.

[blake.]

My friends pulsar does this when he swaps the leads around. Quiet funny.


Just check the coils are firing the right cylinders

[haveaparty]

Mine was on a pulsar too lol

[trikzlane]

could also be coilpacks

[munki]

ok

check injector's for solid connections
Check coils for cracks and leads for resistance
x4 ignitor modules are known for being sensitive and will shit themselves without much prodding.

Yeah mate I had the same thing happen with my 4agze and it was from water getting into the spark plug gallery, washed my engine bay and wasnt careful. So I would be checking the spark like everyone else has stated, but yes on 3 cylinders it will sound like a rexy.
