[Brut4c]

I'm making this separate from my other p0300 post (https://www.camaro6.com/forums/showthread.php?t=588397) because this might be helpful to others unable to resolve a p0300. My dealer, Schumacher Chevrolet of Denville is claiming that the TSB was just released last month. Unfortunately for my son his car is still not fixed. Today they changed rocker arm solenoids on cyl 1&5 and an my son took the car back out this evening and the MIL is back on. But maybe this direction will get someone else up and running with no light.
