OK so its about 10 degree's out and I start my Camaro to warm and charge it up and my LLT V6 engine is jumping really bad. Couldn't be good for the timing chain.
Then the idle comes down, engine smoothed out and I get the MIL lit up.
I remember there was a service bulletin for this (P10284) and I set DTC P0306 cylinder 6 misfire.
Forecast is for daytime highs only in the 20's.
No big deal, its off to the dealer for a re-flash of the ECU computer.
I'll have to wait for the roads to dry out and the salt to dust off them though.
Here are some pics.
