Rough Idle when warm but fine when A/C is turned on

Hi Everyone,
I have an issue with my Caldina st215, when its warm the idle drops and it starts missing. The revs sit at about 600-700rpm. When I turn on the Air conditioning the car idles up a bit and the miss is gone and the car idles perfectly.

I've tried bringing up the rpm holding the accelerator to the same rpm as the a/c idle but it is still missing.

Any reason why this might be happening and how i may be able to solve it?

Thanks again
Adrian

Dude, have you adjusted the idle screw? Pulled the idle control valve and cleaned it out with TB cleaner?

i would look at cleaning the idle control valve and maybe the throttle body as well.

I couldn't find the idle screw itself, I didn't get the chance to clean out the idle control valve. That will be something I will get onto asap.

Its been bugging me for ages haha.

Thanks
