Rough Idling problem solved and then came back?

My 85 Camaro has rough idling at low speeds and sometimes it even stalls out when I brake at stops.

I have already put in new air filters, oil change, filled all fluids, replaced Idle Air Control, replaced Throttle Position Sensor, and got a new Mass Air Flow Sensor.

What is odd however is that I put in a new PCV Valve and my Camaro ran beautiful for 2 days. The problem just came back like a curse. I checked the PCV valve again and everything was fine.

Any explanation for this?
Also would a compression test help me out finding any more issues?
