    yes there are 4 02s. Yes that code concerns the 02s but that doesn't mean that is the problem. I had that same code a few months ago 0157 and 0137 too. The problem was my MAF. So start by cleaning that. Use electronic contact cleaner - its like $10 at radio shack. Then report back.

    "maf" = Mass Air Flow sensor. Its between your intake lid and the throttle body.
