    07 wrx cruise is blinking and check engine light is on.. help please

    So my check engine light turned on a few weeks ago and the cruise control light did too....
    I got it scanned and what showed up was:

    P0031
    HO2S Heater Control
    Circuit Low (Bank 1, Sensor 1)

    I was told that it was the Oxigen Sensor so i replaced it today...
    The flashing cruise and check engine lights went off so i thought i had fixed it
    but a few minutes later they came back on...

    I tried to reset the ECU by unplugging the battery and pumping the brakes for 30 seconds and again it went away
    for a little but then again it came back on.

    Any ideas?

    most of the time if you have a flashing check engine light, it means you are doing damage to your vehicle so if it's flashing, I would advise you not to drive it at all if you have been. make sure cruise control is turned off.

    Flashing CEL typically means large variance misfire. Usually this means the cylinder isn't firing at all.
