    Default Rough idling and hard start sometimes


    hi guys, ask lang ko, kasi almost 1 month na ang problema ko sa kotse.. civic ESI, 1.6, SOHC, carb..

    about a month ago, nag pa change oil ko and change spark plugs.. ung previous plugs ko is NGK standard plugs, then ang bagong plugs ko ngayon is NGK G-Power (platinum alloy). after a few days, nag start na ang sakit ng ulo ko.. the engine started to hard start, parang palyado and if naka start na, magusok talaga na color black. ok sya if tumatakbo, no problem sa running condition nya, pero if mag stop ako ng saglit, bababa talaga ung RPM at parang mamamatay talaga ang kotse if hndi ako mag rev. then if tatakbo ako, ok na naman sya.. bakit kaya?

    fixes done sa kotse: = magastos and sakit na sa bulsa..
    • repair starter (daot na, pero naayos na din, pero hard start parin, with the same symptoms)
    • changed fuel filter (daot na sad, but still may problem parin)
    • changed valve seals and adjust clearance (daot na sad)
    • changed HTW
    • cleaned the carb and made sure every o-rings are okay

    after doing all those, may konting improvement na, like, less na ang usok at malakas na ang sipa ng starter. pero andyan parin ung Main Problem ko, hard start na parang palyado and rough idling at times..

    please help.. may butas na bulsa ko at yumayaman na ang gas station kasi kalas na din ang kotse ko sa gas lately.. hays..

    I had this problem before with an EK3, problem was dirty / faulty sensors and a problematic computer box. Save money and go B16 hehe...

    hard start- check fuel pump kay mostly mao na ang culprit
    rough idling- check servo if there is a way to clean it then much better, then spray sensors with contact cleaners, if still the same, then computer box might be the culprit. You may go to a good mechanic to check it like Textar, Noecor or JV repair shop.

    ang MAF sensor boss limpyuhi.. MAF = Mass Air Flow. search lang kung unsaon.

    checked my spark plugs a while ago. and it was very dirty. luckily, i have my old spark plugs which are ok pa. so, i switched back to my old plugs. i don't think i have sensors and computer box. carb kasi ung engine ko.. still observing the car.

    boss don, problema guro ana kay ang carb ass'y gyud...

    mao man sad na problema sa akong LX sa una, mukalit lang ug kapawng while gadagan...rough idling man sad 'to sa akoa nya didto ko sa textar nakapa-ilis ug surplus nga carb (pangitaon baya na nga part kay phase out na)...

    anyway, try lang adto sa textar sa mambaling, ilawom anang bag-o nga flyover padung SRP access road...naa sad sila'y thread sa buy n sell section, pwede sad i-search lang nimo para makuha sad nimo ilang contact number...

    although daku2x akong nagasto pailis ug carb (more or less P6k), at least nasulbad akong problema...

    hi guys, update lang sa akoang car prob..

    kakagaling lang namin sa shop ng friend namin na nag-tutune ng honda.. anyways, ito ung probs. first of, ung adjustment ng float ko sa carb ko, medyo hndi na tama, may nag usab.. kaya pala namamatay lalo na if mag rev ako. the more ako mag rev, the more sya mamamatay.. reason behind pala is "starvation" sa gas.. nauubusan ng gas ung carb ko kasi mali na ung adjustment ng float ko sa carb. finally, naayos din namin.. salamat talaga sa friend ko at ok na ung takbo ng kotse ko.. weeee..

    another thing, ung jet ko sa carb ko is I think hndi talaga para sakanya, meaning i always run RICH on gas.. kaya umiitim ung plugs ko.. next ko na gagawin is to change my jet, para sakto lang ung fuel and air mixture.. then, konting tune-up nlng..

    i learned a lot about sa engine ko, and hopefully this will also help other pips na nagkakaproblema din ng ganito.. thanks sa mga comments nyo guys..

    tama ka pre, siguro nga daku na lungag sa jet ko.. papalitan namin un ng maliit na konti, ung sakto lang para sa kanya..
