misfires on snap on scan tool?
have my heads/cam ls1 on a snap on scan tool and it's reading misfires on all cylinders especially cylinder 4, my question is is it doing this because of the heads/ cam and the tune, or do I have a problem. I've never had it on a real time scan tool and have no reference to look back a determine if it is reading different. the car does seem to have a miss but not as serious as this scan tool would indicate. anybody ever have their hands cam tuned ls1 on a real time scanner and read misfires?
