    Hi mga sirs, I own an isuzu Ls pick-up with a 4ja1 engine.

    ang problem ko, kapag matrapik and naka-stop lang ako, napapansin ko na pag tumatagal eh bumababa ang idling ko. from 700rpm to 500rpm gradually. pero kung tumakbo na ako ng matagal tumataas naman sya ng bahagya. specially kapag naka-off ang makina and then i-start ko after some hours bumabalik naman sa dating idling nya.

    ano po kaya ang problem?

    thanks sa mga replies.

    try nyo muna mag-tune up

    change fuel filter, air filter, oil filter and engine oil

    then bleed nyo yung fuel line
