    good day ho mga sir.. tanong ko lang ho bakit baliktad ang idling ng sasakyan ko..pag naka aircon po bumababa rpm maga 500 tpos pag off ng fan ng aircon babalik ulit sa 750..
    tsaka last na lang po, ano po ba dapt ko gawin kasi pag nka stop un kotse lalo na pag traffic, kelangan ko pa apakan ng konti un gas para lan ma maintain nya un 750 na rpm. pag binitawan ko baba rpm hanggang mga 250 tapos di na gagana fan ng aircon so iinit na sa loob ng kotse.. i tried na itaas un menor pero konting pihit pa lang masyado naman tataas mga 2000 rpm na by the way matic po sasakyan ko..
    maraming salamat po sa maitutulong nyo..paxenxa na ho kung maguluhan kayo sa tanong ko..

    just have your car tuned-up at ipa-adjust mo na rin idling sa mechanic mo.

    CARB or INJECTOR ?
    Sounds like your idle air control valve might be dirty.

    Your car should an A/C idle-up valve that increases the idle RPMs when you engage the A/C. This is part of the vacuum system on fuel-injected cars, so on yours it's probably connected to or part of the carb. Check that and any attached hoses for clogs/tears.

    same thing here sir pero diesel yung sa akin, 4jai na isuzu. kapag trapik bumababa ang idling pero kapag umaandar naman ok sya. i noticed na kapag walang AC kahit trapik hindi naman bumababa ang idling ng ride ko.

    Sabi ng iba sira daw ang drier ng AC ko...any comments on this? thanks

    the culprit kaya pla bumababa ang idling kapag stand still and with AC on is the aux fan. hindi na sya umiikot kapag naka-AC ako. check nyo muna sir yung aux fan kung gumagana. ok na ulit yung sa akin.

    The Civic LXi is FI. Better have the throttle cleaned specially yung mga sensors.

    pag OBDII compliant kailangan scan test muna para sure . no guessing

    Kung carb sana yan, madali lang ang pag-adjust, pihitin mo lang pahigpit ng kaunti ang compressor idle-up. PagFI, baka kailangan lang linisin ang servo or worse palit servo na.
