My guess is (and it is just a guess) is that since you flipped the AC switch on there's probably a wire connection to the switch that is routed through relays (or not) to the ECU and is probably telling it that the AC is on and so the ECU is trying to compensate for the extra load of the compressor which is not engaging so you're probably getting a "miss" in the engine firing too soon or too late a because of this "miss-information".....
