I have a '92 Firebird with the 3.1L that I just put an engine in. It has the electronic EGR, not the one with all the vacuum lines and stuff.. I was wondering if I were to eliminate it would it throw a code in my ECM and turn my "Check Engine" light on?

yes it will if its broken or leaking ur best bet is to make a thin blockoff plate to install on the pipe from the egr to the intake manifold so u can leave the egr pluged in

even with the egr plugged in it will still throw a code after a little bit of driving... ive found that if i dont let my car engine brake at all(i have a 5speed) i can keep the light from coming on, gotta be clutch happy though

Just remove it, block off plate on exhaust manifold and throttle body, then disable the code in the ECM, or if you don't have tuning equipment I would get a megasquirt ECM, definitely a worthwhile investment if you plan to beef up your car.

What kind of equipment is needed for ECM tuning?
