i've followed what OTEP & sequoia said..check kung may kuryente ok naman meron. & did some of wildthing's tips...so far ang faulty pala eh yung mga spark plugs..coz after i check everything bumili na ko ng mga kelangan. from spark plugs & fuel filter. cguro kelangan na rin palitan yung fuel filter saka pa tune-up ko na rin cguro para less-hassle in the future..thanks pala for all your help.
