I wondered the same thing on my 1992 4 cylinder.. if there was any form of sensor besides just the computer telling spark plug 1-fire now or 2-fire now,ect. I think if you have the electronic ignition like I have its just the computer.. but im not certain of this.
Computer controlled and not adjustable
You can replace the ignition lock cylinder in your 1994 Pontiac Firebird without removing the steering will. Remove the retaining ring at the top of the ignition cylinder. The ignition cylinder will slide out.
Replace the ignition lock cylinder.
Attach the wiring harness to the end of the ignition lock cylinder. Slide the ignition lock cylinder into the slot. Tighten the retaining ring at the top of the cylinder.

It is a common problem in most GM vehicles.
On the column accross from the key lock cylinder
The 1994 Pontiac Grand Am ignition lock cylinder is held in place by the retaining ring at the top of the cylinder. Remove the retaining ring. Remove the wiring harness from the back of the cylinder.
I think you are trying to time the ignition to top dead center. If that is the case the crank position sensor tells the computer when to fire the spark plugs. This sensor gets pulsed by the gear on the crankshaft and depending on where this gear is at in its rotation the crank position sensor lets the computer know where the pistons are at in the cylinder. So the whole thing is computer controlled and a timing light is not used. Of course I'm assuming your car is an OBDII model.
No, not if it is not defective. If the ignition switch is defective then that is all you need to replace.
This is controlled by the computer. You can set the throttle opening to prevent wedging and sticking but this should not change the idle speed.
