AC on and rpms DROP...?
I got a 01 integra type r with b18c5. When i turn on my ac the rpms drop around 200-300 and the motor stuggles to stay on. Im thinking its the alternator but anyone have experience with this problem or know whats wrong with my car??

Re: AC on and rpms DROP...?
check your Idle Up Solenoid, which has 2 positions. closed when no additional air needed. open when additional air is needed (high idle).
seems like it fits your problem.
hope i didn't put u off track.

The A/C just uses a lot of the car's power to work. If the idle decrease isn't too dramatic, it's normal as far as I know. My '01 ITR and plenty of other cars I've owned done the same thing. You'll probably experience the small loss of power when you're driving and put the A/C on 4 (full power). Another belt is rotating, more of the engine's power is being used for A/C at that, and it is normal for it to get to the point where you will notice/feel it.

could be a problem with the compressor, I think it might need to be clean and lubed. I recommend bringing your car to an a/c shop and tell them to put new clean new refrigerant in your system.

Says in my Haynes manual that idle RPM is supposed to rise 50-100 RPM to compensate for the extra load the A/C places on the engine.
However it also says the idle should be 550RPM +/-50 RPM. Mine idles at 1200 RPM and with the A/C on it drops to 800 so I have a more normal idle with the A/C on which I dont understand

My Type r idles at about 7-800rpm when engine is good and warmed up. It only idles at 1100-1200rpm when I first start it up and engine is cold. 550rpm seems a tad low to me.
There is definetly something not right with hon-daddys Type-r. It should still have a smooth idle with the a/c on, and not struggle to stay running.
