Just letting you guys know that I replaced the in-tank fuel pump in my 87 Scirocco 16V and my bucking problems went away.
Symptoms - When the car was cold it would buck sporadically about three or four times after I got the car moving. There would be a violent jolt and the car wouldn't rev until I pushed in the clutch. After I went about half of a mile, the bucking would stop.
FYI the screen on the old pump was not clogged at all (about 3 or 4 specks on it) so there must have been some type of internal problem. I never did test the old pump though, I just replaced it on a hunch.
