Has anyone seen this before or is this one off? None of the other XJ6 had this.

 

That is a work around instead of replacing the spring inside the throttle butterfly shaft tower

The original internal spring has been superseded by a stronger internal spring by a TSB

This ensures the TPS comes back to idle stop for proper idle and not be high

Does the cruise control work as the linkage looks wonky ?

 

Took off the fuel rail to get the injectors rebuilt. But it does work

 

I did that on a few cars while I was at the dealer when the replacement spring was back ordered.(my own cure)
Jaguar issued a TSB for intermittent high idle. (stiffer spring)
The spring setup (shown) is for the AJ6 throttle.
It is easily adapted to the AJ16.

 

Is there anyway to take this apart? I have a spring that’s broken on the upper part.

You will probably have to buy the while TB assembly.

To know if you have the upgrade spring you can compare spring thickness with a micrometer

To know the donor car has be done there will be a sticker on the radiator area , if they followed instructions completely

You can always replace the existing spring with a stronger one if you have a present idle issue

Spring thickness is not the only variable for the spring strength

 

I guess it does not come off. Anyone have a top of a throttle body they want to sell? My pick and pull does not have any xj6

 

There was someone with pics and instructions as he removed and reclocked / repositioned tighter the original shaft spring

I won't be back for a couple of hours and find it

It is the upper spring that is broken. I need to figure out how to take the “top hat” off. But even if I do I will need to find a spring which I will have to find another complete top hat anyways. That is why I think I just need another one

 

Anyone have one that they could part with
