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?

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.
