Ok, so I've got a 95 GSR. I'm sitting at a light in neutral and all of a sudden my idle just starts jumping. It goes from 500 to 900 rpm and keeps jumping. Me and my roommate figured out it has to do with the a/c, when I turn the a/c off the problem stops. We popped the hood while the idling problem was happening and the a/c compresser just keeps turning on and off and you can see that it slows then speeds up the pulleys. What's my problem and how can I fix it. Thanks.
