    Codes...arrhhh.....WTF?

    Ok so 300 miles into a drive last night I tripped two codes P0503 and P1133

    The 503 is what has me confused its something about VSS low signal??? What is going on there?

    The 1133 I'm thinking might be because I have the ZZP midlength combo and 3inch catback its something about oxygen sensor inefficiency or something, I could always just kill it in HP tuners

    Anyone have some insight here?

    Your P0503 sounds like it could be bad connection, or sensor going out.
    P1133 could be becaise of the exhaust flow, but could also be a bad sensor. I use to get this code on my J when my primary O2 sensor was going out.

    Yep, my z24 use to get the P1133 code right before the front o2 sensor failed.
