    Default RPM fluctuates in Baleno (When A/C is ON)

    Salam All,




    I have Baleno GLI-P, 1999-done 90K; for past couple of days I am frequently facing problem of RPM fluctuation both on CNG and petrol. One important observation is that the problem only occurs when A/C is operation and it vanishes when A/C is switched off; also, sometimes it works normally (No RPM fluctuation) even when the A/C is operational.









    Can some experienced Baleno users help me out in diagnosing the problem.

    Regards,


    /a




    Ashar.

    fluctuate as in missing? or it dances ( sorry didnt get any other word) while the car is standing or moving? same thing hapend wid my friends civic, most probably throtle body sensors need service, or by max need replacement.
    Get over the fact that Xli lacks power windows, Its an Xli because it lacks thoose features or else it would be a Gli or an Altis if had all the goodies.

    Dear Chinyoti,


    I liked the word "Dancing" and will continue with it. By the way i got the throttle body serviced around 2 months ago. Also, if the problem is with throttle body then it must not immediately stop "Dancing" with switching off the A/C.


    Please advise.


    Rgds,

    Gents,




    The problem has been streamlined a bit. I closely observed the phenomenon while keeping the hood open. It has been observed that while the fluctuation is in progress a continuous tick-tick-tick sound keeps on coming from the engine; probably the A/C is continuously turning on and off. However, the phenomenon disappears after some time and the A/C starts running normally with no fluctuating RPM problem.




    Your comments are appreciated after the new observation.




    Rgds,

    There can be two reasons only for tht tic tic voice The fuel being sprayed is insufficent to handle the load of A/C so get car tunned Air fuel setting and spark plus.The other can be VSS aka Auto choke typo which regulates the AlC and CAR RPMS it be getting weaker..

    Get the A/C clutch checked,i think its coil is getting load due to bad electrical contact or corrosion in pavement causing for voltage drop.
