Are you getting a P0300 code or a specific P0301 thru P0308 code?

I also show Misfires around 500-1200RPM when idling sometimes! I don't throw any codes, but I have seen my total misfires counter hit 22! Could it be my plugs? I noticed since I changed them, I've gotten crappy gas mileage. I might switch out to TR55's. Autolites seem to be better than my original plugs, but not by much.

Actually, come to think of it we had an issue with one of our 2002 LS1 club cars tossing a PO300 at idle when it was stock. We never did figure out what it was, but the P0300 was removed when the cam went in.

I remember hearing about other 2002 cars with this issue.
