I have a 99 PSD and am looking to see if any one has the ability do perform a Cylinder Contribution Test and or Buzz test on my injectors. An auto engenuity program would be even better to check the rotational velocity of each injector. I have a slight miss @1200 rpm, in nuetral-parked. The miss is barely noticeable idleing @650rpm. Dissapears above 1200 rpm. FTE-PSD forum is pretty sure it is an injector not wiring.
