I was told by someone that engine rpm should go slightly 1000 up and come down, when I start the AC in car engine idle state. My car AC does not give that nature.. After i keep some time to get the engine idle to an rpm of around 600, and when i start AC on, then rpm only goes up around 700 not upto 1000. Is this an unusual condition?
P.S. I was focused on this because I have a lil bit sound and a lil vibration when AC is on. ( also my ac fan belt has tiny cracks inside going to replace it but rpm problem is not caused by it i think.) Appreciate if somebody could comment on this..
Also the car was stopped suddenly when AC is on and in idle state. It has happened 3 times. Going to hv an engine scan as well.
