Truck is giving an intermittent P0442 "evap small leak" diagnostic trouble code. Spoke with another mechanic who helped isolate it to the vapor canister purge valve solenoid located on the driver's side of engine underneath the intake. This is the only component of the evap system not located in the back near the fuel tank / spare tire area.
Symptoms include rough running and an occasional misfire due to exhaust gasses entering the combustion chamber at the incorrect time. P0442 and P0304.
Disregard the part in the video about the bracket. RockAuto sent me the wrong part!
Video recorded 3/20/2020. Let's hope this fixes my problem! :-)
