Hey Scotty k I'm a big fan of you & your video always have found the way to fix my cars with your videos also learned tips on buying cars .... but I got a question for you ....
I can't fix my truck this time tho.... it's a 2006 f 150 2wd 4.6l ... it's reading code PO171 & PO174 ... I had just changed the MAF sensor . Also the truck is not responding to acceleration right I mean when doing 80 mph gas pedal is all the way down and won't go over 80 like if the truck is weak???? Any idea ???
