Default Engine trouble - 1995 Chevrolet Blazer 4x2 - 4.3L Vortec

First the problem started with a faulty catalytic converter which was replaced with an OEM part, and new exhaust all the way back to the tip.

Now I've noticed the motor is running rough to the point of almost cutting off at idle.

What are some things I could check? I've already checked the O2 Sensor.
