Idle with AC on below 600 rpm
I was stopping at a traffic today, AC was running when all of a sudden, I can feel the brake release a little leaving my foot pressing down more and the rpm going down a little below 600rpm and then, it went up to 800rpm where it should be when the AC is on. When I accelerated, the rpm was revving high going from first gear onward and it was back to normal again. On the next traffic light, it happened again, rpm going down below 600 and back up around 800 while the AC was on. Is this normal or should I be worried? Thanks, guys.
