Throttle position sensor - desparately looking for one
my grand old 1985 5000 was working up until last week when it had to be towed.
Shop says I need to replace the throttle position sensor but Audi does not have them anymore. Can I use a different year than 1985 or are there places I can still get either a used one or after market part?? Help! they want my car out of there.

Shop may be wrong...
Taking in account that that is a non turbo KZ engine, you have a combination of idle and full throttle switch on the throttle body. Having any one of them fail would not disable the car from starting and running. Yes, it would have all sorts of other bad effects, but the car would be still driveable. Could you elaborate the details of the condition?

Re: Can you describe more...
problem started as hi rev idling irregular up and down idle, then went to extremely fast idle so I had to shift into neutral at a stop or hold down brake. Now it seems to cut out gas to carburator so car stalls out. Finally stalled out and wouldn't start thus the tow

Re: Shop may be wrong...
car finally stalled and is not driveable. Just before this for a few days, it would stall then start after about 2 minutes of sitting (with irate people honking behind) Appeared to be something inhibiting the gas flow like the old fashion paper floating in the gas tank.
Then as mentioned before, there was irregular idling going from very fast to dying out unless I manually pressed on the accelerator to hold the idle at a constant.
Shop described part as part physically monitoring throttle position and sending info to engine chip board

Sounds like multiple problems happening here.
Zoran is right, you have no TPS, it's just an idle/WOT switch.
The poor idle can be from vacuum leaks, and/or a bad idle stablizer valve. Probably have a bad O2 sensor, and very possibly one of the engine temp sensors are bad, sending the ECU bad info.
