    rough idle

    i just bought a 02 wrx and when i bought it they told me that the ac pump was bad and that i would have to replace it. but ive noticed that if i turn my heater on that the engine kinda suppters a little and the headlights will dim a little. even if the heater isnt on the car kinda idles rough, but im going to do a full tune up on it and ill keep you posted if that helps it.
