mga sir to correct ignition timing, what do you do? do i have to change the timing belt po ba or i-correct lang clearances ng mga valves?

normal lang naman po di ba na magkaron ng ingay ang valves/tapets kapag uphill tapos mababa po ang gear nyo?

sir gudday,you may change timing belt if it has reached the runnung hours,otherwise kung medyo ok pa wag na muna.the toppet clearance when the last adjustment? you have to take note or make a record..you can make adjustment with the timing as long you have an inductive timing light.you just check on your underhood decal how many degrees would the adjustment, its either BTDC or ATDC chek mo lang ilang degrees.By the way,dont forget na itutok yun timing light sa timing marks.The timing light has instruction how to use.Check mo rin you tube for video clips panu gawin adjustments.advise ko lang wag masyado asa sa mga mekaniko d lahat yan marunong or nag-aral or has a proper training.mas ok kung matoto at kaw mismo gumawa.

I did also change my timing belt.. Possible din ba to adjust the timing? Coz medyo parang may maingay na sounds like ng mga valves/tapets! Possible ba na yun ung problem nya? Beside biglang bagsak idling ko pag naka aircon.. D15b dual vtec engine.. TIA!

Sir Pahelp po. ano po reason kung bakit mababa yung idle ng toyota vios ko 2009. Nasa 600 rpm lang po yung pointer nya. medyo hirap po ako kapag uphill muntik na ako mag stall. napalitan narin po yung spark plug at nacleaning na rin yung throttle valve.  ginawa ko disconnect ko yung batt terminal para reset yung ECU pero ganun parin rpm nasa 600 rpm. ano reason kung bkit ganon yung idle.
