Gear working perfect but Vtec works lately @ 6.2K but it must work as i know between 4.5K or 5.4K rpm ?? The car is 100% Stock

well im not sure when the vtec works in that car, but above 6k is too high. normally the check engine light would come on. i know on the newer cars the vtec only works if you are at full throttle and the car is warmed up with enough oil. maybe check the oil level?

Oil is new ... No warnings in the car ... Gearbox oil also new
may be there is ECU Problem ???

I bought the car soon ... if the previous owner plugged out the (-) Battery cable may cause the problem ?? i plugged out The (+) Cable as there was problem with airbags then i fixed it ...

- No errors on Scan Tool ??
** Why VTEC Works lately !!!!!!!!!!!!!!!!!
