    If you have got the throttle body serviced and all that, make sure that the recommended spark plugs gap is 1.00 mm to 1.1 mm.
    In addition ask your mechanic to perform the following calibrations with a diagnostic computer:
    - Zero point calibration.
    - CVT oil pressure calibration ( If it is CVT equipped car).
    - Sensor G and Yaw rate sensor calibration.
    Hope that works.

    here is the issue that was diagnosed after visiting abu bakar, and lots of efi electricians.

    My AC compressor is jam which when turned on causes load on engine due to which it vibrates and shakes. When AC Is off, there is not vibration. Abu baker told me that i would need to change compressor, condensor if needed and vales etc. expecting 20K.
