If we're talking about the same thing, I got a lot of hits searching for
'throttle valve switch', which is what the Bentley calls it.... tho some
folks seem to call it the 'throttle position switch'.
Did you say you got a new one? I opened mine and there was a lot of crap in
there for something that looks like a sealed unit. It's a weird little
mechanism- the plunger pushes the side of a spring which moves a lever in or
lets it out. Mine was sticking apparently because of some goop on the wee
contacts. Damn difficult finding something to clean in a space that small.
I also found with testing that even with it adjusted properly on the bench,
in the vehicle it didn't go back to 'open/no resistance' at the idle stop
unless I let the throttle kind of 'snap back' in place- so I think it's
still sticking.
Dunno if this helps you any but I thought I'd throw it out there.

Good luck,
Robert
