A good used throttle body with switch is one option.
I have a few good ones for sale.
I think we are talking about a 2.1 here,  ( though  1985 1.9 uses the same
switch arrangement, with a smaller throttle plate, so we could be talking
about one of those instead.  - those are kinda rare, but I have one of those
for sale too  )
