Step 1. Wait for the engine to cool down and gather listed materials. Working on a hot engine is incred- ibly dumb. Step 2. Open the hood and remove the front panel and airbox. (Fig. 1.) Step 3. Protect the air intake with a cover (I used aluminum foil. (Fig. 2.) Fig. 1. Engine all assembled Step 4. Locate the spark plugs. This engine has six-cylindars and twelve spark plugs (six on each side). Select one side to do at a time. Step 5. Starting with the spark plug furthest from the firewall, remove the electrical plug and unscrew unit from the engine using the T-25 Torx bit. Use the magnet to ensure the screw is not dropped into the engine. (Fig. 3.) Step 6. Spray the spark plug boots with WD-40 to loosen them for removal. Wait a few minutes to allow solvent to penetrate. Step 7. Use the 17 mm wrench to pry the boot off from the spark plug. This is the biggest pain in the ass. Try to loosen the boot by turning the boot using your hand. Be careful not to damage or crimp the boot if using the pliers. Fig. 2. Protect your engine! Cover the air intake from accidental beer spilling! Fig. 3. Spark plugs on driver’s side with wires and harnesses intact. Step 8. engine. position labeled, engine. Do this for the entire side of the This part took the longest. Label the of the modules. The boots are both on the module and on the (Fig. 4 and 5.) Fig. 5. The engine has embossed lettering to show which boot goes where. Fig. 6. Old and new spark plugs. I used OEM spark plugs, as seen in Fig. 7. Fig. 4. Engine without spark plug modules. Step 9. Remove the spark plug. This is a pain in the ass as well. Remember, lefty- loosy, righty-tighty. Use the appropriate-sized extension to remove the spark plug. You may have to change extensions mid way. Step 10. Insert new spark plug. Spray with WD-40 before screwing in to allow for easier removal the next time you change spark plugs. Tighten to 28 N m. Step 11. Re-attach boots to the spark plugs, making sure you place them in the right order. You will feel or hear a pop when they connect. Also re-attach modules to the engine block. Step 12. Repeat on other side of engine, noting the number of new and used spark plugs as you go along. Step 13. Once complete, remove cover that was placed on the air intake and replace air box. You are done! There will be some smoke and smell as the WD-40 burns off the engine and plugs.

ISSUE Some 2005-2008 F-Super Duty 250/350 vehicles equipped with a 5.4L 3V or 6.8L 3V engine may experience premature automatic shut off of the fuel fill nozzle, or repeated fuel shut off at the fuel station delivery nozzle with malfunction indicator lamp (MIL) on with diagnostic trouble code (DTC) P0191. Vehicles operated in muddy or dusty environments can encounter a dirt clogged carbon canister system. More specifically, the carbon canister’s vent, fresh air box, and filters become clogged with dirt from operating in such environments. SERVICE PROCEDURE Inspect the vehicle canister system and if it found to be dirt clogged then continue with this TSB. NOTE IF THE VEHICLE’S CANISTER SYSTEM IS NOT DIRT CLOGGED, THEN PROCEED WITH NORMAL DIAGNOSTICS AND DO NOT CONTINUE WITH THIS TSB. Vehicles with Pickup Boxes: 1. Replace the carbon canister assembly with a canister built after 10/1/2006. This canister has a revised internal filter media, and went into production on 10/1/2006. The date code is on a black sticker located on the carbon canister assembly. 2. Relocate the fresh-air intake port to a more protected location using the fresh air hose kit, for pickup applications only. 3. Replace fuel cap assembly if the vehicle was built before 5/16/2007. Vehicles with Pickup Box Removed or Chassis Cab: 1. Replace the carbon canister assembly with a canister built after 10/1/2006. This canister has a revised internal filter media, and went into production on 10/1/2006. The date code is on a black sticker located on the carbon canister assembly. 2. Relocate the fresh-air intake port to a more protected location using QVM bulletin Q-132 at the body builder’s website – https://www.fleet.ford.com/truckbbas/index.htm for fresh air intake routing recommendations. 3. Replace fuel cap assembly if the vehicle was built before 5/16/2007.
