Thread: Misfire

  1. #1

    Default Misfire

    hello, I'm getting code p0135b that is causing my engine to missfire and then throws a missfire code. I've checked a ton of things, but don't know how to get rid of this!!!
    I've got a Chevy Suburban 03 AWD 5.3L
    Please help.

    P0135b is the code for the O2 sensor, bank 1 sensor 1. Probably need to replace this O2 sensor. It is the one on the drivers side exhaust closest to the engine.

    I already changed the O2 sensors. Let me know if you think of something else, thank you!

    not to be a pain, but new does not always mean good. i had many new parts that were junk. did you test the old one? you might have a wire or connector issue as well......mike
