I just changed my catalyst converter and noticed that my engine goes off when my A/C is on and I decelerate or apply the brakes, the rpm rises and drops just as the engine stops, the emission appears to be rough as well as the movement.

Check for vacuum leaks at the pcv hose to the throttle body. Common failure.

The idle air control may be bad as well. Is the check engine light on?
