2004 Ford F-150 FX4 5.4L Poor Fuel Economy, no power
Customer said lack of power & fuel mileage down. Test drove vehicle while driving actuator never turns on. Know actuator only actuates after 2600 rpms. Replaced intake runner actuator and checked runners as dealer said this is common problem. Still same issue.
