My car, a 1.9 tdi Golg with a 2052 turbo and modded 1.9 pump body with all 11mm internals from a Land Rover (I think it was a LR 300). It's running very well most of the summer except for hesitation under mid to light load. If I roll on the throttle from 2000 rpm fairly fast it doesn't do it, but if I back off slightly it will start to sound like it's missing. I've got .250 Hflox nozzles, new this spring and it's got a lift pump feeding the pump.
I have some smoke under full throttle (I thiink it's okay -maybe LDA needs to be backed off a bit). I do have the governor mod with this pump as well.
I'm just needing some direction - this hesitation - will timing make a difference or is it likely a pump setting that's off?
Any help in heading the right direction is apprecieated.
