According to Chilton's the 1992 3.1L Firebird has a 0.045 gap for the spark plugs.

Thanks. Where is the O2 sensor on them? I'm assuming back by the catalytic converter. Going to be fun to get out 15 years later

On my '91, the O2 sensor is in the exhaust pipe right where the two pipes from the exhaust manifolds come together. From underneath the car on the passenger side, I can see the O2 sensor as I look up towards the exhaust manifold.

That's where it was and came out alot easier than I thought it was going to. A nice PB Blaster bath probably helped a little. She runs like new again, guess I don't have to rush putting the 383 in yet.
