would it be cause of a bad tune that i have a multi misfire in my 2000 ss m6? its an all cam car. it has a crane cam with .600 lift and 112 lsa, full bolt ons. the misfire seems to only happen at idle. i was told by someone that the reason for the misfire at idle is because the cam is aggressive. when u look at the rpm needle it does not move at all but still shows misfire and turns on service engine soon light on. can anyone help me?

Yes, it is because of the cam. You need to get the misfire tables changed to stop the SES light. When your car was tuned for the cam, it should have been taken care of.
