I just replaced mine on my '91 2.1

The problem was that in my old throttle body the butterfly is hinged on some
kind of plastic/nylon shaft that goes all the way through to the throttle
switch.

this shaft wore out, and the butterfly started catching on the inside of the
TB and made a groove in there and started binding up.

The replacement I got from a kind list member has a metal shaft going all
the way through.

I can only guess that the people with problems have the plastic/nylon shaft
instead of a metal one.

-could be wrong though..
