    Cool OBDII Codes

    I have a 2000 T/A with K&N filter and descreened MAF . I've been running Superchips performance tune for a couple of months now. This morning I got an SES light. I scanned for codes and found two of them, PO172 and PO175: "Running rich on right and left banks".
    Any ideas on where to start checking?

    What mods? I would clean the maf and ditch the k&n. I'v heard alot of issues with per. chips here lately.
    Is it a custom tune?

    Might be the MAF descreening - maybe their tune assumes it's stock? Then maybe not since it's been a couple months? Something easy would be to return the PCM to stock tuning and see if it comes back if you're running the canned tune.

    Not a custom tune. Just Superchip's tune. I set the shift points and firmness.
    I will clean the MAF and see if that helps. I normally clean the MAF a few days after cleaning and re-oiling the K&N. But I didn't do it the last time which was a few weeks ago. I hadn't thought of that. Most likely that is the cause.
    Thanks for the help.

    Looks like cleaning the MAF took care of it. No SES light so far.
    Thanks again for the help.
