    Check engine light came on as I was going to work. Stopped by
    Autozone and they read a 172 code - too rich.

    Flipped and grabbed other vehicle.

    What should I be checking tonight when I get home?

    TIA

    You don't have a K and N air filter do you? If so you have too much oil in
    it. Throw it away and clean the MAF sensor.
    If not , it still could be a dirty or bad MAF sensor. Or simple a vacuum
    hose leak. or maybe a dozen other things.
    What's your mileage? if not over 60K, take it back to the dealer (after you
    get rid of the K and N filter)

    Actual milage is around 92,000. It turned out to be a plogged air
    filter. The input side of the box was full of cottony seed fluff and
    that seems to have filled up the air filter. I cleaned it out and
    changed the filter last night. Also reseated the MAF sensor cable.
    Put around 200 miles on it today and it seems OK.
