Throttle Body Cable Adjustment = Original Power Restored ?

I don't think enging knocking should be an issue. The car was designed and built to handle the power of a fully open throttle. After I adjusted mine I briefly experienced knocking, but it went away pretty quickly.

I looked at the video on Youtube, my 97 XK8 Conv does not have that set up. It is like the pics of the Supercharger one here with the STRAP TIE holding the throttle cable. I HOPE THAT IS NOT FACTORY in that they use a strap tie to hold that. My 97 has the rubber covered cable coming out of firewall that is feed through the bracket where that STRAP TIE is at at which that point the little cable can be seen. On mine at that bracket, I have nuts on boths sides of the bracket to adjust for the tension on the cable. I see a little play in mine.
But man if they put STRAP TIES on these from the factory that is **** poor at the price level of these cars.

I am curious if you did the final step of the adjustment which is pressing the pedal slowly all the way (without the engine running of course). It is my understanding that this readjusts the cable to the right amount (at least this same step was used in the last car I had where the adjustment mechanism was similar).

Then what is the purpose of the final step required by the JTIS--which states CAUTION: THE ACCELERATOR CABLE MUST BE ADJUSTED BY PRESSING THE ACCELERATOR PEDAL. . . And also the requirement that the adjustment is supposed to be done using the "special tool" that builds in some residual slack? So according to the JTIS the actual adjustment is being done when the cable is pressed so something must be happening.

I don't think so since Step 1 of the JTIS procedure is "Make sure the kickdown plunger is fully seated to the retaining stud shoulder". In other words, the last step of the procedure (pushing the pedal all the way down through the kickdown position) counts on the fact that the kickdown plunger is ALREADY correctly positioned.

Hi Fellas, I just did this adjustment on my 2001 XJ8 4.0 and have to say I'm very pleased with the results!! Before whenever I wanted a bit of power I had to really press the pedal hard and even then it would just grumble. But now its instant power and everything works like fluid. Thanks to all who have helped this post along, it;s worth so much!! S.
