ISSUE
Some 2010 E-Series vehicles equipped with 4.6L, 5.4L or 6.8L gas engine and built on or before 6/22/2010 may exhibit a lack of power on acceleration due to an engine air cleaner inlet restriction at the upper air deflector on the radiator core support.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
1. Open hood and remove the S-shaped air cleaner inlet tube from the upper air deflector using a twisting motion.
2. Inspect the air inlet opening in the upper air deflector for the flexible plastic/rubber flap that may be out of position and obstructing the air inlet opening.
a. If the flap is obstructing the opening, reposition by directing it down in front of the A/C condenser.
b. If the flap is correctly positioned, this article does not apply. Refer to normal diagnostics in the Powertrain Controls/Emissions Diagnosis (PC/ED) Manual.
3. On vehicles with 6.8L engines and the air deflector was repositioned, remove the remaining throttle body inlet pipe. Refer to Workshop Manual (WSM), Section 303-12.
4. Inspect the corrugated throttle body inlet pipe for damage. Be sure to extend the accordion pipe to inspect for tears or holes. Replace the throttle body inlet pipe if a tear or hole is found. Refer to WSM, Section 303-12. (Figure 1)
