    Default Alto vibration when AC is on

    Salaam,

    I bought alto 2008 recently and went to suzuki 3S workshop for service and tuning. The tuning was fine but there was one problem.
    Its pickup on CNG without AC was ok but with AC it was very low. With two person in car it becomes annoyingly slow. So after few days I get back to the suzuki workshop and tell them this problem. Mechanic check the car and made some few adjustments. After that pickup is much better.
    But mechanic also mentioned that 'AC par gari khari nahi hogi' means when AC is on then in idle position there is some vibration in engine. he said that it is because car has local ac and blah blah.
    Now without AC engine is very smooth but when AC is on there is some vibration but vibration level is very small. In fact if mechanic did not mention it I would not have noticed it.

    But now that I have known about it I have some questions.

    Is it normal to have little vibration in engine when AC is on?
    How can I reduce this vibration? I heard there is some screw in alto for setting idle rpm. Where is it and can i experiment with this to reduce vibration.
    If vibration is reduced will it impact on pickup or fuel consumption?

    Thanks

    Vibration can be due to decrease in idle rpm when AC turned on, just go to any local mechanic and ask him to slightly adjust idle rpm while ac on. Remember that idle rpm without ac is adjusted from carb and idle rpm for ac is adjusted from the vacuum diaphragm linkage with throttle lever.
    Performance is the never ending game with never ending charm!!!

    Thank you all for your replies.

    If I increase the rpm will it affect pickup?
    I am wondering if it is so simple then why the mechanic did not fix it.
