    You haven't been through a carwash recently have you?

    Any other signs of problems other than the CEL? Are you running the stock intake or some sort of short ram/CAI?

    Youve maxed out your intake.

    On cold days, with that turbo, youll be maxing it out.

    You can either reset your ecu or upgrade to a bigger intake

    It's also possible that you managed to get some water into the intake and onto the MAF. I had it happen a couple of times with an SPT intake until I started putting a shield over the filter when I'd go into certain washes. I'd leave the wash and it'd feel like the engine would almost kill and the light would come on.

    Sounds about right too. I was testing some data logging thing on my iphone when it happened. So I was all the way on it!!

    That could be too. I don't have a shield over my filter
