No adjustment on my 93 or Josh'*. Just 2 screws for mounting.
See Autozone'* TPS Replacement/Testing Guide

Does this make the 93 the 'perfect car'?
Last year of the PCM flash feature
Last year of the diagnostic mode on the ECC
First year of the non-adjustable TPS
Last year with no exhaust resonator
Last year of a one-wire (cheap) O2

...and '93 was also the last year of the more expensive 3-solenoid digital EGR valve too, right? :(
In regards to the TPS adjustment, my '92 needed it and my '93 didn't.
When I replaced the TPS on my '92 it ran ok for a day or so until the SES light came on. It was then that I learned that the TPS is adjustable and the voltage on mine was out of range and tripped an error code. Other than the SES light it seemed to run normally at the time.
Also note that the service manuals I have state different specs for the nominal voltage range. I have the actual Pontiac manual and also 2 different Chilton'* manuals. I don't remember which book I used when I adjusted mine.
Adjust it with the ignition in the ON position, but the engine doesn't have to be running. The engine should be warm, though (so the TPS potentiometer is at operating temperature).
If you use a digital multimeter, you'll need to strip a small section of insulation from 2 of the TPS wires and then tape them afterwards, or push small wires into the connector body to make the measurement.
The adjustment only takes a few minutes.

I like my R-12 (cuz I still have a source for it if I need it) and the digital EGR. I haven't seen one that needed anything more than cleaning, but the linears get replaced from time to time. Our digital EGR'* are very easy to troubleshoot and fix.
