Hello, when the vehicle is idling rough with the A/C on, it's basically a case of the load that air conditioning systems put on the engine accentuating a larger often hidden problem with engine performance. Testing should be performed to verify and validate proper fuel delivery, air flow, and ignition spark providing proper engine performance. Additionally, if there is somehow a problem with your compressor for the air conditioning system causing excessive drag or load on the engine, this can cause the idle to be too low also and cause rough running.
