Subject:      85 vanagon throttle body swap... top mounted vs bottom mounted
              TPS ????

Hi Volks,

I checked the archives but have not seen a complete answer to this
question. ETKA diagrams don't seem to answer it either.

My Dad's 1985 automatic sunroof vanagon has been having problems with
the throttle linkage. Apparently the problem is at the throttle body.
This morning it hung up at high RPMS and would not dislodge until the
engine lid was lifted and the lever reset by hand. Once it was reset,
everything was fine. I suspect that the brass butterfly is rubbing
against the aluminum casing and the friction has become enough to
overcome the tension of the return spring.

I have a spare 1.9L engine with a throttle body that is in very good
condition. Unfortunately, the TB on the sunroof van has the throttle
position switches underneath, and this TB has the TPS located on top.

BEFORE we pull it all apart... is it possible/practical to swap these
units, or should we plan to repair the original TB instead?

Happy Trails,
