I just installed an h22 motor in my civic, idles great until I turn on the ac. I have the idle set about 1000 rpm then I will put the ac on then it will go down beyond 200 rpm like its about to die, then will eventually die. I set my idle at 1500 then when the ac kicks on it would go about 800 rpms then its ok. But I am worried about the negative effects of having a car idle at 1500 all the time. I know that a stock car would idle between 750-1000 rpm. Well I guess what I am trying to ask if there is negative effects for having my motor idle at 1500 all the time. Trying to save my motor and not put to much stress on it. Any positive advice would be appreciated

 

when your driving with ac on can your feel any major power loss besides the normal power loss??

if so i think it would be your compressor about to go or the clutches in it

 

the normal power loss, and the compressor makes a wheezing noise. it gets cold after a while cause its hot here in texas but its just annoying at the stoplight because it keeps on dying and vibrating my car.
