So, i would never use my a/c kasi, i stall..n my RPMs would go down too much. Putcha, i took it back to my mechanic n told him to fix that. So right now its fine. I guess u just have to find the perfect tuning for the idle, so that the car's idle is fine with the a/c on n a/c off.
Then another time, like u said, my idle without the a/c was about.. 1000RPMs plus. then when the a/c is on, it would go down n be fine. i guess they were trying to compensate the idle with the a/c on. I've had so many problems with my idle, but, finally its perfect.
Hopefully ur problem gets fixed. just take it back to the mechanic n tell them about your problem, n that you didnt have that problem before u took it to them.
