Valve cover gaskets and harnesses.
I've had the rear driver's side harness give me fits the last couple of days (missing/cutting out intermittently at certain RPM) and today on the way back from town it finally petered-out. I hate driving 12 miles on one bank of cylinders.......
But I wasn't stopping in a blizzard at 18 degrees to play with it along side the road.
Wouldn't you know, 2 miles from the house it started working again.
