Question about replacing 90 throttle body?

[nube90]

Hey guys, I need to replace my throttle body on my 90TSi because the biss screw is missing and the guy that owned it before me filled the place where its suppose to be with some kind of putty so now its basically junk but anyways I was wondering if I have to use a 90 throttle body or if I can use one of a 91-94.

If you use a 91+ TB you will have to fix your wiring harness for the ISC and TPS and use the later fuel rail so it doesn't hit the TPS but you'll be better off in the long run.

If you need one pm me....Can get them for pretty cheap....

And any harness youd need.

Are you sure he filled it with putty, or is it just the factory cap that is over the BISS screw??? There is a factory cap that keeps water and debris out, and mine is like a plasticy but rubbery type cap. Check that first before you buy a new TB. Just a thought.

Yea im sure I got the dremel out and started drilling into the putty where the screw is suppose to be and never found a screw but didnt want to go to far with out a new TB.
