    Hello fellow tsikoters! Need ur expertise on my idling issue. So far what I did, was to clean the throttle body, idling improves however bumabalik un pgka rough lalo pgnsa minor ako.

    Observation: pgngppalit ako ng spark plugs, gmganda nnmn ang idling ko, khit heavy traffic no problem khit on ang aircon.

    Ano ba sa tingin nyo pde ko pang gawin o ipacheck? Btw, my car is grandis chariot. Thanks guys!!

    Have your sensors checked with a trusted mechanic sir. Quickstart in Sucat in known for Mitsubishi concerns.

    Peace out!

    I think he meant MAF sensors, IACS (Idle Air Control Sensor), Idle Speed Sensor, O2 sensor, etc..

    Try to diagnose using the following list sir:

    when you say rough idling what do you mean? erratic idling kasi is different from rough idling.
    pag erratic idling, sa mga sensors yan specially sa MAF.
    pag rough idling, baka mahigpit yung aircon belt mo o tumitigas na yung compressor pulley resulting in na hindi magandang idling.

    imho.

    Erratic - Akyat baba ang RPM sa tachometer or yung menor mo taas baba
    Rough - Isang eksena lang na tunog na parang hirap ang makina

    Correct me if I'm wrong.

    I think erratic po yun sa inyo..

    Yung rough po kasi hindi ka makaka-experience ng taas baba ng RPM.

    ok lang magvibrate ang engine, walang kaso dun, as long as hindi excessive na
    hanggang cabin ramdam na ramdam.

    nagiiba ba ng idling pag nageengage yung ac compressor?

    your engine is supposed to idle up a little bit higher to compensate for the load your ac compressors gives to the engine.

    900 - 950rpm usually ang idling pag ac engage.

    nararanasan kodin yang gayan, pag patay naman ang erkon para naman nag hihingalo ang makina. alangang mamatay o hindi pero kapag nirebolushon lumalakas naman, pag bukas naman erkon at nag otomatik gayon din ang nangyayari sa kanya, pina tsek ko naman compressor, evapoartor, thermostac ayos naman daw sabi technician ng erkon savi baka daw serbo, ganun ba talaga yun?

    Do the corona test or water mist test sa gabi.

    Buy a sprinkler, yung tipong ginagamit sa orchids na pang spray or sa pag plantsa.

    Then sa gabi, madilim.. may mumu este start mo engine at spray mo ng water mist yun high tension wires. Pag may nakita ka sparkies yun na yun.
