I follow this list dailey and know to search the archives before asking BUT,I have searched through the archives and have not found the exact description of my problem so here it is:I have a 90 MV with stock 2.1 and manual transmission with 157,333 mi.  When I am driving at any speed and let off of the gas, the engine jerks substantially.  If I push in the clutch it goes away. If I accelerate it goes away.  If I am driving at a steady speed it does not happen unless I barley start to let off the gas.  It happens in all gears.  I can put on the cruise and it will jerk a little when it accelerates/decelerates.  It idles fine and goes through all gears with normal acceleration fine.Any advice would be great.  Thanks for all of the great info over the past three years that I have been foolowing,
