Hi All, So my 2013 3.5L 65K miles, was having a bit of a rough idle. I know this is common for these engines, so I figured I would post my findings. A few days ago, I cleaned the MAF and two MAP sensors. Seemed to help a little, but it was still rough. So yesterday I replaced the MAP sensor mounted on the intake manifold, because I didn't like how the old one cleaned up. That made a big difference. Today, I changed the plugs...found two that were way wide...Gapped the new plugs at .028 (per Makuloco), cleared the PCM memory and bingo! Smooth as silk.

If you have a rough idle, maybe this will help.
