I'm trying to diagnose some problems with my '90 and want to make sure I
completely understand how the throttle valve switch works, and what it does.
Bentley sez:

- injection quantity for idle
- switch off injection during deceleration
- ignition point setting on idle

And here's the question: would a faulty throttle switch cause a high idle?
Would it potentially cause excess injection on start-up? I have the other
symptoms which Bentley describes (cold stall, warm lack of deceleration fuel
shutoff). I have to pick up new leads for my voltmeter tomorrow and want to
make sure I'm thinking right before I start measuring.

Thanks!
