  • If the engine is operating a large number of accessories, particularly air conditioning, the idle speed must be raised to ensure that the engine generates enough power to run smoothly and operate the accessories.

    If Idle Air Control (IAC) is working properly: Idle speed (Aircon On) > Idle speed (Aircon Off)

    If Idle Air Control (IAC) is not working properly: Idle speed (Aircon On) < Idle speed (Aircon Off)



    update ko lang po,

    kanina pinaandar ko yung kotse, (vios 2008 1.5g matic) pinaiinit ko ang makina,

    when idle
    aircon off - 900 rpm

    aircon on - drops to 650 then rise to 800 rpm

    aircon off again - rise to 1.1 k then drops to 900 rpm.


    sana makuha lang sa linis ng TB, IACV, MAF sensor etc.
  • share lang.. my DIY Gap Gauge for measuring the gap of spark plug.

    got some old catalogs and measured the paper thickness using a caliper. i found one that used 0.1mm thick paper. now i can measure gaps, 0.1mm to 1.8mm easily.
