    hello po mga sir! hope you're all having a great time>

    my prob po kasi oto ko; its a 2000 SiR with a B16a engine.
    actually kakukuha ko lang po recently ung oto from a friend of my cousin.
    the problem now is when i reach that predetermined RPM (usually hanggan 5K) di po ngbubukas ung VTEC nya. HELP po in this problem.

    also,pag nsa highway ako n medyo mabilis ang hataw, nagj-jerk ung oto na parang nawawala ung power, tpos bigla2 po ulit bumabalik.

    di ko po matanong dating my ari kasi nsa states na po cya. ask ko po sana opinions nyo before ko i-punta sa talyer.

    thanks po sa mga tulong nyo mga sir!

    I think hindi predetermined ang pag kick ng VTEC maraming factor kung kelan sya magkikick like throttle position, oil pressure, etc. Sa akin hindi usually 5K somewhere 5.8K rpm ata sya usually nagkikick.

    As for the hesitation pag nagaaccelerate ka baka wala sa timing yung engine, you can have it checked with a timing gun.

    Wait ka pa ng ibang suggestion maraming experts dito

    wala ba check engine? try to tap a LED light sa vtec solenoid para malaman talaga kung gumagana o hindi. try mo i-hataw hangang 7000 rpm, kung wala pa rin baka sira yung sliding pin.

    as for the jerking, medyo marami pwede culprit yan eh. from oil pressure to timing... pacheck sa mechanic na lang kung loosing power pa rin at high speeds.

    question vtec owners, i'm just curious..paano ba malalaman pag nag kick na yung VTEC? may indicator ba or lalakas ng husto hatak or what? sorry for this question..i'm just really curious because i haven't handled a vtec yet..

    seat of the pants feel.. mararamdaman mo pagsipa ng vtec sa acceleration.. other than that... there is no other indicator like a VTEC ON light...
