  PS.  On the way home a moose ran out and took off down the road in front of us and ran full speed into the ditch, tripped in a hole and totally landed on it's face and slid along the ground :lol:  :lol: I've never seen that before!! She didn't get hurt 'cause she bounce right up and ran off.

  
  
  uhhh... i'm pretty sure that must've hurt some  :lol:  :shock:

• I am trying to figure out the same thing on my 94 AAZ. every now and then she "runs right" and pulls really haRD!  But i do have some injector knock that I have been tryin to get rid of.
  
  I ran diesel purge through it and it sounded so good runnin the pure purge, no knock!
  but afterwards it came back.

  your injectors might just be worn out?
  
  if they dont atomize fuel properly, they will knock loud.

• no the words bosch weren't on them
  On a side note. I'd like to refresh my fuel system
  I wouldn't mind opening up my pump and replacing rotor vanes, camplate, rollers etc.
  None of this is hard at all.  Done lots of them in school. THe cool thing about these VE's is the only setting that isn't machined into them is LDA and internal pressure
  I would just leave my pressure regulator where it is and measure afterwards.
  
  MY big question. WHere can I buy the parts to redo a pump?
