hmmm...seems broken. you could probably pick up a used 5.3 pretty cheap.
just kidding. arent 300 codes misfires? i thought po300 was random misfire
and the last number indicates the cylinder ie; po301 would cylinder number
1 and po304 would be number 4... just my .02

P0309 Cylinder # 9 Misfire
P0304 Cylinder # 4 Misfire
P0300 Multiple Cylinder Misfire
Hmmm didn't you just put in a new cam? Maybe they broke something or left something loose? Bad plugs? Broken plugs? Broken plug wires? Damaged coils?

I know with the LSx system once you cam you need to turn down the Misfire Detection when installing larger cams. Otherwise youll pickup a lot of false misfire during idle with the stock setting for the stock cam.

As for smoke if it were my car doing it at Idle only, i would be checking the valve steam seals to make sure they were seated correctly!! Especially if its LSx 4th Gen Fbody after a cam install. Those suckers can be a PITA to get seated in tight areas.

How are we to know? Not in his sig. Guess we are supposed to memorize every members' non LS car? Also, is easy to diagnose for anyone familiar to engines... Another reason for one to assume the video was posted for entertainment purposes only.
