    mga guru,

    ask ko lang, ano kaya possible cause nito...

    whenever i floor the brake while the engine is on idle (car not running) bumababa ung rpm ng engine. kapag naka aircon naman ako and i brake the engine stops.

    TIA!

    mitsu lancer '89 glx ride ko...

    the brake uses power from the engine to boost the brake fluid pressure.

    isn't your idle speed a little high? di ba dapat around 800 to 900 rpm?

    Your idling is too high, have it checked.

    taas ng idling, siguro kinalikot yan ng mekaniko mo (sana hindi ikaw yun ehehehe) para maremedyuhan yung namamatay na engine mo.

    add mo din sa i-check mo, ignition timing baka off kaya need na high idle yan engine mo. when was your last tune up?

    mataas yung idling ko kasi sira yung solenoid valve na automatic na nagbubukas when you open the a/c.

    but now, i decided not to use the a/c (kasi nga namamatay when i floor the brake). 800 - 900 ang rpm idling speed ko.

    i'll check yung vacuum hose na yun, by now hindi ko pa maCheck. busy kasi sa work.

    carb yung auto ko.

    tnx sa mga respondents!!!
