    CEL will give you a low rev limit and basically fuck your whole shit up
    i have not encountered that code before but...

    quick google search

    Check your VTEC oil pressure switch.

    The way the VTEC oil pressure switch works is that it is a normally closed switch. The ECM sends a voltage to the switch and expects the voltage to go through the switch to ground. If the ECM reads a voltage on that circuit when the VTEC system should not be operating, it will turn on the "check engine" light and set a code. This code will be a P1259 on a vehicle with OBD-II. So if it isn't reading the voltage going to the ground, then it may think the vtec is activating when it shouldn't be. That's why it sputters around those RPM's.
