AC stumble problem?

[T.X.240guy]

I just got a 95 240Sx and when I turn the AC off it idles around 600 and 100 rpm. I replaced the battery terminals, distributor cap and rotor, plugged some fuel injector cleaner right into the fuel rail, cleaned the throttle body, and nothing helps. the car runs fine until i turn the AC off, until tonight! i put a full tank of gas in it and it's starting to stumble with the AC on too. theres about 139,000 miles on the engine any inputs?

sounds like you may have a problem with your IACV or your accessory air control valve

they're usually on the same assembly. you need to contact a dealer for that part. good luck they're expensive.
