You're saying a sync problem, so surely you're already doubting cam or crank signals ?
So have you checked these ? Are you getting a usable signal from both ?
And if it isnt getting a suitable crank/cam for sparks, then it could not be fueling correctly either.
Is there any sort of logging or a scope to check these signals ? Or any error reporting or diagnostics for invalid crank/cam triggers ?
