Proper Idle RPM
Fully warmed up to operating temperature, what is the proper rpm at idle, in park, and in gear for a 2006 F150, 4.6 liter V8 (2V), w/ 4WD & Automatic trans (w/ all accessories off, if that matters).
Thank you.
Thank you.

1) Edge Evolution
2) Hold the trip counter button while starting the truck up, then once started press the trip counter until the RPM's display.
Holding the button down during start up enables the test mode to come up and will last as long as the truck is on. So next start up it'll be back to normal.

Rpm
You can also adjust your rpms with the Edge Evolution, but only higher than stock, not lower.

I used my secret Powers.....I thought everyone had them
Actually just as Cavtrooper said but in reverse..I first set the Trip computer to Diagnostic then when I got the Edge I just have the RPM on always ...mainly cause I do not have the RPM guage due to havin an STX.
May the force be with you.

Idle RPM
Thanks to all for your replies. I too got 600 RPM, warmed up, and in park. It's around 525 in gear. That just seems low, but it must be OK if ya'll are in that ballpark. The dealer wouldn't tell me the spec. I used a laser based stobe with reflective tape on the harmonic balancer ring - a common practice in vibration analysis.
I was fishing to see if maybe my RPM was too low, and tied to the vavle train ticking nosie, which dissipates a few RPM above idle, as if a few more PSI or GPM of oil with the increased RPM clears the lifter tapping.
Am I nuts?
Thanks again.

The 4.6L motors are also covered in those TSB, but the key is the 3-valves / cylinder feature, rather than the conventional 2-valves / cyl config.
Nevertheless, thank you very much for responding.
Other than the idle tick, I love the truck - ride quality, sound system and creature* comforts for a so-called bare bones model. Then again, the comparison datum is my previous truck - an '87 GM C10 4WD.
Yours truly,
