Trouble code
Can anyone explain trouble code p0621 to me. Car started running loki it was not hitting on all cylinders. The check engine lite flashed on and off 3-4 times as i pulled into driveway. Check trouble codes and this was what I got. The flashing engine lite only when on and off about 4 times and stopped on its own. Any ideas.....2007 6 speed LS2 Thanks VNVETT
