hey guys need so advice on this one. at crusing speed on higway say bout 80kmph my B16A suddenly jumps to between 200-400 rpm higher stays for bout 2 sec then drops and keeps fluctuating like that for a while even with my foot steady on gas pedal!! almost feels like vtec is continuosly engaging and dis-engaging. help!!! anyone had experience with this before? any help will be greatly appreciated.
At 80kmph you should not be near VTEC. Sounds like a tps (or tune up needed). Give us some more info like under what conditions, whether it happened suddenly or gradually, engine mods etc.
