OK, so this is very odd so let me try to explain. This weekend after running at 3800 RPMS for about 15 mins we pulled into a local harbor to refuel. Once we reduced speed; to idle I noticed that the starboard engine would shudder slightly and the synch gauge would swing all the way to the starboard side. This happened two or three times on our way to the fuel dock. The long black for this engine has been replaced in the last 20 or so hours; at the same time the serpentine belt was replaced as well as the idler pulley. Any ideas on what this could be on a 2001 310, vdirves and Horizon 5.7s?
