Hi,

I'm having problem with engine pull or performance whenever i turn the aircon on. rpm would dwindle town to 500 during idle. also i feel some sort of vibration when accelerating with aircon and would subside on the rest of the gear. im thinking its the pulley or belt when aircon is on o could be mounting..

thanks..

it may be from eh compressor kicking on that the extra vibration. belts should be changed every 60k along with tensioner. try cleaning throttle plate and iac hole with choke cleaner on both sides.
