I have a BMW 320i 1992 model running KM 190000, lately i have notice that the idling of the car is going up and down especially when the AC compressor is running but when you turn off the AC the idle is normal (0.6 1/min x 1000). already consulted a mechanic he advised that there is a problem in the air flow switch, he tried to put a fuel injection cleaner on the fuel to rectify the problem but still it is the same condition. would need your professional help on this matter. thanks!
