My newly acquired 4.8 does this strange thing first thing in the morning. As I put the key in the ignition and turn the key to one position before start the dash lights come on as usual, but the rev counter does two cycles of zero two 1500rpm. I thought it might be signifying an error code but can't find anything on the net.
