Re: Jerking Jetta!!!!
Don't try to adjust the injection pump! At least don't try to adjust the flow.
I'd check the timing before anything else. Make sure all your timing marks are correct, then check the timing on the pump. You loosen 3 (?) bolts that allow the pump to rotate then adjust the timing. It's been a few years since I've worked on a diesel, but I think they describe it in one of the autoparts store manuals. The Haynes doesn't do the diesel. I can't remember the name of the manual that does, but it's one other very common ones.
Did your replace the fuel filter? Have you checked the fuel lines? Air may be getting sucked in. The pump pulls the fuel all the way from the tank and there is a lot of fuel line in between. Did you have the lines bled properly when the other work was done?
