So the truck stumbles when the MAF is connected but runs good when you disconnect it?
I had the same problem it turned out that to be the intake tube I was using was larger then original so it was getting more air than it thought. I had a spectra cold air intake and the kit I had didn’t have the plastic reducer that fit in the tube around the MAF. As soon as I put that in it ran fine.
What intake are you using? What MAF?
