    Check your fuel filter and fuel pump.

    Several possibilities from a fuel pump, to crank sensor, to a clogged fuel filter, to ignition (is the Optra direct ignition or utilizes an ignition coil?). You will have to observe and check these items one by one and have a scan done as well perhaps.

    Well, that leaves you no choice but to bring it over for a repair. Better if you could have it towed.

    Since may check engine light na, theoretically mas madali na ma-pinpoint kung ano ang problema talaga ng car kapag mapabasa mo sa shop na may obd ii scanner

    to be or not to be, that always confuses me!

    korek ka diyan bro. obd scanner lang ang makakasagot sa sa check engine ng car ni TS at ng malaman niya ang error code.

    kapag nalaman ang error code, pwede ng itanong kay google o kaya sa mga tsikoteers

    Hi-tension wire yan, pag mabilis ka nag hi-tension si kaya nasira na, pero pag traffic ok lang

    Palit ka hi-tension wire

    it's only a band-aid fix nandiyan pa rin yan not unless malaman mo yung error code na nag-cause ng CEL.

    better to have it checked, kc usually ang check engine light kht mawala yan nag pepersist parin ung problem, I experienced na nag ddownshift ako when i run to tagaytay AT light turned on and CEL also, then pina reset ko ung computer ng car ko then nawala CEL but the problem of downshifting still persist so as soon as i went back to my place dinala ko agad sa mekaniko ko then only to find out that one of my sensor is already malfunctioning. and some bands inside the transmission. so bring it to ur nearest talyer kesa lumala sira lalo na at mukang engine yan

    Seems like you have a clogged tank breather. The fuel tank is vented into the atmosphere for the fuel pump to suck gasoline.

    If said vent is clogged, your fuel pump is restricted. In some cases, gas tanks are known to crumple.

    pwede ka talaga mag CEL sa gas cap na hindi maayos pagkaka balik. It is a common trigger, so kung hindi na naulit that might be it. to be extra safe pa scan kung may code.
