While your google pulls up a lot of picture with TPS visible, all the ones I looked at are from VWvortex which ran a different version of the engine. It is a 2 stage TB not a single plate like a recent TB has.
My 90s reference was maybe a bit of a sweeping statement, the technology in that car is ancient.
Hopefully the OP can tell us what he has
