[Vwdiesel] vibration

No starting problems, at least non that I'm aware of. It starts right up
cold and takes a second longer to start when warm, but it has always done
that. The IP has been overhauled, for what it cost me it better not be bad.
:(  Can I adjust that lever stop that the throttle lever rests on or does it
mess with something inside the pump?


Check your fuel lines for bubbles. Also, could be your FI pump is on its way
south.  Your symptom sounds like something I've seen trying to start my 1.5
NA in my genset that makes it a hard starter.  When I got the engine the FI
pump was in terrible shape.  Fortunately it recovered and now works great
except for this little quirk. Below a certain RPM on starting (throttle at
idle stop) the pump doesn't seem to be able to get enough pressure and fuel
delivery to the injectors and the engine shudders and almost dies.  Rev it
up a bit and the problem clears quickly as fuel pressure climbs and things
start to work.

Are you noticing any starting difficulties also?
