: : After nearly a year, I have now changed the Air felow meter(used), the Air valve(new)and the air control unit(used) but the idel still fluxuates from 800 to as high as 1200 rpm. I took this MF to the dealer and they said I need to change both the control unit and the control valve which I did. They also said there is no air leak. If you have solved this problem please share your knowledge. Thanks
