    Have you done any recent maintenance lately? Check your Vtec solenoid.

    There should be filters inside the solenoid. One is under the solenoid and the other is between the vtec assembly and head. Loosen the three bolts and clean the filter with a solvent.

    if you have never changed the vtec solenoid gasket then you need to do this. its most likely clogged. there is a screen that is attached to the gasket and catches most the trash

    look at 10 and 12. this is the gasket and screen.

    checked the gasket first. if its clogged its not going to allow good flow of oil to the solenoid
