Re: Boost drops '91 200 tq

[Wolff <quattro200@earthlink.net>]

The potentiometer is located within the throttle switch housing on the
'91 200 (possibly other motronic cars as well). According to Scott M. it
tells the ECU how rapidly you are mashing the throttle. If you buy a new
throttle wot/idle switch, you get a new pot as well since it is built
in.
