Put half a bottle of seafoam down the PCV valve hose
With the engine running, a bunch of white smoke will likely come out
The tail pipes. The more crap in your truck the more smoke.
Also for the next few fillups, pour a bottle of it into your tank.
It will help get rid of the moisture from all the ethonal and will
Also clean your injectors.

with these FI systems it'd be something a sensor reader at a dealership or if you know someone with a plug in (not your cheap OBD readers, im talking about one of the $250+), they can tell you what all your sensors are reading at. clogged exhuast/fuel filter/air filter
