Rough idle?
Leading details - 2007 F150, 5.4L, V8, 4WD, 120k miles
My truck has been having an idling issue for several months now. This especially happens after it 'warms up' and has been run a distance at highway speed. Reverse is also an issue. RPMs are dipping below 500 and will occasionally stall if not goosed. We have replaced the plugs and wires, throttle body, MAF, and Fuel Control Module. These were all potential issues that we thought could be causing the issue. No check engine light, no codes that we have seen. It's still there...the Lazarus of idle issues! Any suggestions? O2 sensors?
