When I start accelerating from a dead stop (1st gear) the Vanagon gets the jitters.  Sounds like a warped flywheel to me; but just wondering if it could be oil leaking on the clutch.  I don't have the problem in any other gear.  The problem seems to be worse when I am accelerating uphill from stop.
Some days the problem is worse than others. 

I had a new clutch and throwout bearing installed several years ago.

I would appreciate any comments for solving this problem.
