When the AC is switched on the compressor takes some power of engine and hence piickup reduces by some margine.For the redued pickup the fuel supply system ie throttle body needs to be inspected/serviced.

You need to get your compressor motor and Throttle body checked for this problem.

Check the belts for all drives may be needing change

Answer by S SRIDHARAN 03 March 2010

The AC hasa been fitted thru a non cowned dealer who do not normally check all the systems.Check the throttle,compressor motor and belt. Further it would be advisable to go to a company authorised dealer to help you out with this. They may send you to an outside source who is attached with them, who may be more competent and will check the system correctly.
