I was going to suggest you use a scanner to read throttle position -- guess I still will. You can read it with the ignition turned on but without starting the engine. I use an Actron CP9145 -- which worked great right out of the box and gives you a bunch of useful real-time info.

I'm pretty sure that the Tech 1 is GM's version of a scanner. It's used to read the throttle angle percentage.

Where in the FSM did you read that it was needed so the EBTCM can re-learn the throttle position? I can't find it in mine - also a '94. I'm on page 5E2-139.
