Test your FICM.

Watching on my CTS now. 48v cranking and reads 49 well driving. Cleared the codes and they haven't been back yet, so I'm hoping its the connector on the ficm.

You might just have a loose connection somewhere, injectors 2,3,5, and 8 are all on one plug... 1,4,6, and 7 are on the other.

It will show you which plug to look at. Could be a chaffed wire harness or something too.

Threw the codes again before I made it home. Pulled the connectors at the ficm and cleaned them. Monitored for a while on ae and it seems to be ok so far.
