I would start with the coils. Almost all problems seem to be from that area. Maybe buy one at car salvage and shot gun it out. I think it's worth a try. Need to start eliminating possible causes. Yes alot of codes - need to find a commom dinomatator. Good luck

This P0507 code is one that's sometimes triggered on vehicles that have electronic throttle control. That is, they don't have a regular throttle cable from the accelerator pedal to the engine. They rely on sensors and electronics to control the throttle. In this case, the P0507 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is greater than the desired (pre-programmed) RPM. In the case of GM vehicles (and possibly others) if the idle speed is over 200 rpm higher than expected, this code will be set.

I don't know why you would replace all the coils,I do know,
but I don't do diagnostics that way.
The TACM (throttle actuator control motor) is part of the
throttle body, and can not be replaced
The PO2104,PO2107,PO2110,PO2111, are TACM related codes
I won't write a book on it,you got what they are, from your
friends scan tool
If all the coils are good,then they are not spiking the PCM,
coming back on the TPS Sensor and putting it into ETC Failsafe
(that senerio the dealers are not up on )
I would buy some CRC Throttle Body Cleaner, and spray the
throttle plate, won't fix your issues, but does on a ford explorer
Hopefully you can slowly move the throttle plate and free it up
The throttle body is about $470,up from $325 a year ago,from
It only has 4 ,10mm bolts,so you can solve this at home
Forget the Cam Code for now
I would back probe the TPS Sensor, with a couple needles,
and use your volt meter to check
It has two sides--0v to 5v & 5v to 0v
one 5v ref from pcm,one ground, you can stay on,and red lead
to either of the other wires to test TSP voltage drop,eg .5v to 4.9v
when moving throttle plate
I will check back with you or give you my #

For this problem, I looked at the Code results. There are a few parts which can cause it, and in some cases the Dealer will need to install a Data Logger if microwave signals are suspected.
Ford has made modifications to this Throttle body, and parts were backordered for a redesigned throttle body. This may be covered under a Silent warranty and a one on one request for factory assistance.
Or you may try to replace the cheapest part, the throttle position sensor, Several people on the F150 forum changed out that part and it worked. Myself, even changing the sensor, I would want the best throttle body made for my truck. So rather than a patch, if a free factory replacement were offered, I'd take that.
Contact your favorite Dealer and see what they will do for you.
