Vehicle started with engine code P0171 the bank 1 lean code. Finally got worse while driving for sputtering so I replaced the MAF and PCV and it ran fine for one day, about 12 miles test driving. Today on way home it got really bad with hesitations in engine, and tailpipe now has a PUT PUT noise coming from it. I was thinking of replacing sparkplugs and maybe wires. Your one video on my truck model only shows removal of the plug with the coil pack, the drivers side of my vehicle does not have coil packs over those 3.
have the same problem?
