First off, welcome back Oink! Haven't seen you around here for a long time.
Next, you can adjust the TPS voltage on our cars and it does sorta work but it doesn't last long. If you have the pre-94 intake & throttle body, you can loosen the TPS and rotate it to adjust the idle voltage to be 1.0v. On the 94-95 setup, there is no factory adjustment. The computer reads the TPS voltage at start up and treats it as if it was 1.0v. It does the math to compensate for the voltage difference.
Example: Let's say your TPS reads 0.94v at start up. The computer sees the 0.94v and sees that it needs to add 0.06v to get to 1.0v. So, you lightly press the gas, the TPS reads 1.07v. The computer adds 0.06v to get 1.13v, and uses that amount to determine spark, fuel, etc. You accelerate again, the TPS reads 1.5v. The computer adds and comes up with 1.56v. Etc, etc.
You can adjust the TPS on 94-95 cars, it involves slotting the TPS bolt holes so you can rotate the TPS like you can on pre-94 cars. But since the computer adjusts the voltage internally, it won't do much good. At most it might temporarily fix the problem.
I would test the TPS voltage anyway, if it's really far off of 1.0v or it's not a steady voltage, the TPS is failing and needs to be replaced.
