Thread: WBO2 sensor help!

  1. #1


    Has anyone else had trouble burning up their WBO2 sensor? I've been through two in the last four months and I've only put about 150 miles.

    I guess I should rephrase the question above. Has anyone had problems with the Holley WBO2 sensors, or is it just dumb luck that I've had two go out on me in the last 4 months? I run premium gas 91 octane or 93 if I can find it. What could possibly be causing them to go bad? At $250 a pop, I’m getting tired of replacing them.

    Running HP and all Holley EFI sensors, 7” Digital Dash on a SBC 383 mild cam. It'll run great and then all at once it starts spitting & sputtering, the tune is corrupted and I can’t get it to run right until I replace the WBO2 sensor.
