Jaguar 1997 Throttle Body Rebuild

This information is from Mike McGee known as OregonJag on 

He thought he would share what seems so far to be a successful repair to my í97 throttle body APP. There tends to be a lot of traffic on this forum regarding problems with the TB and my car was not immune to them. This turned into quite an epistle so Iíve broken it up into entries of symptoms, removal and testing, alleged repair and results. 

The APP or Accelerator Pedal Position sensor is part of the throttle body. Other cars it is called a TPS or throttle position sensor. On these it is much more complex. 

Let me repeat that this is for a í97 and I have no idea if this is useful for other years with the 4.0 engine. The TBs on the 4.2 and supercharged cars are surely different and may not be a problem to begin with. My VIN number ends in 016878 putting it late in the model year. As far as I know this is the original throttle body for the car.
