This car has a small engine. So when the AC compressor kicks on, you really feel it in the gas pedal. The engine isn't surging, the compressor is cycling on and off, thus changing the engine's load. The load of the compressor takes horsepower that would normally be used to move the car forward. so you have to apply more throttle to compensate. If the compressor didn't cycle on and off, the AC system would ice up and quit working. Perfectly normal, but something you generally don't feel in a car with a larger, more powerful engine.
Just enjoy the working AC that your Metro likely didn't have!
