    I e had this truck for about 5 months but I just drive around town so far. I’d like to pull a small trailer but I noticed it is sometimes sluggish from take off. Started to take off faster lately to test things out. At one point last week I got a check engine. Engine would dog out then sometimes surge to the power I’d expect from a 6.2.

    Codes are 101, 172 and 175 Over all it has seemed to run pretty well.
    Ideas?

    All of those point to the MAF sensor.

    Anywhere air is getting in past the MAF sensor. I had this once and my intake tube after the sensor was loose check for cracks too.

    Cleaned and reinstalled the original MAF that I replaced a couple weeks ago because of a p0101. So far no codes and it doesn’t hesitate anymore???

    Wonder if the original MAF was just a loose connection. If you can take the other one back do so. You know it’s no good. No hesitation makes sense. Right amount of air and gas. Glad it’s fixed.
