Default 1993 Corvette AIR removal & EGR

I have removed by secondary AIR pump located left front. I have also eliminated EGR and blocked off the two positions on the back of the motor and the manifolds. I am currently waiting for the plates that block the two position on the back of the motor. Other than an SES light that I will correct, what am I to expect once I start this vehicle ? How will the drivability be? I have heard some good and some not so bad stories.

I don't know but I would suspect that you would get at a minimum, some O2 sensor faults.

Originally had a H26 Code but I reattached the plugs that go to the air pump and placed it back in its original place with no plumbing attached and the codes are now gone.
