Replacing TPS?

[judderod]

I seem to remember taking a demel type tool to the rivet heads, using the small cutting wheel disc to make a notch for a flat head screwdriver.

None of them are riveted on !!!
They are held in place with "shear bolts", all the throttle bodies are threaded
There are several ways to undo these bolts but a couple of options are
Cut a slot across the face of the visible head of the bolts and undo with a screwdriver
Or
Drill the head off without going too deep, lift the tps clear and then grip the remaining bolt with pliers and undo
The bolts are not especially tight and in most cases the first option is the easiest
