I'm having some problems with a rough start when the car has been sitting for 8 - 10 hours and it also smokes quite a bit. I have recently replaced my maf, new injectors from kerma tdi, new vacuum lines, and turbo actuator. I think my injection pump might be going out. The car does have 310,000 miles on it. The Injection quantity jumps around from 3.4 all the way to 4.6 when it is warm. From what I understand that is bad and it shouldn't jump around more than .5 Would replacing the injection pump head seal fix this up for me, or is it something internal to the pump?
Thanks,
dave
