More often than not when driving the 97 TD when pressing the gas pedal to pass or go faster the vehicle will fell like its bogging down and not going into passing gear...any thoughts on this one??

My 97 TD went through a period where when I hit the pedal, mainly at highway speeds it sounded like it was spooling up or slipping before it would catch and start to accelerate. Replacing the nuetral safety switch and one of the electrical harnesses solved the issue. Not sure if that is what you are experiencing or not.

 

kind of sounds like a injector or lift pump issue.

 

I am with Injunfarian on this one -- need more detailed information on the problem, but first guesses would be bad diesel fuel, clogged fuel filter (when is the last time you changed it?), or constricted air filter. Next guesses would be lift pump, or other fuel delivery problems (injection pump, injectors, crack in fuel pickup tube)

Is it cold outside where you are? Could be fuel clouding if you don't have a winter additive in there.

 

Well the lift pump is brand new. also this happens in any weather situation..also the fuel filter is new..could it be the kick down cable?? or does it have one?

 

anyone with thoughts on this??
