    Hey all, I've had the EGR light come on before and ended up getting a
    new O2 sensor and the problem went away with that code, but I was
    wondering if there are any other easier ways? I've heard of cleaning
    out the EGR valve but I have no idea what that is or where for that
    matter. I'm not sure what the 121 means but from what I've read it's:


    Faulty signal to/from Air Mass Meter

    Wiring fault to or in AMM

    NO idea what this part is but any help appreciated, thanks
