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

I have 05 LS. I had to codes a few days ago. After doing research on line, somebody, somewhere said it was coil #4. (passenger side nearest firewall). Not throttle position sensor or throttle body. I replaced #4 and tested around the neighborhood at times with RPM over 4k. Did not go into limp home mode. Ford will replace coils free if car has under 100K. I was in a hurry and purchased coil made by Borg Warner (limited lifetime warranty) for around $60.

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 #

On your vehicle, Diagnostic Trouble Code (DTC) P2106 is an "informational code". These type codes are usually accompanied by other codes. If this is the case, ALL of the other codes need to be addressed FIRST. If you are receiving this code without any other codes, there is a LONG list of things that need to be checked to find the cause.
There are a couple of Technical Service Bulletins (TSBs) that would apply to your truck depending on how it is equipped:
If your truck is equipped with an EGR system, TSB 05-3-1 may apply to your situation. This involves testing of your mass airflow circuits and verifying data from both the mass airflow sensor and the EGR System Module (ESM) and possibly repairing circuits with high resistance and/or replacing the ESM.
There is another TSB that may apply to your situation, however this TSB only applies if you are also receiving DTC P2135 along with DTC 2106. This one is TSB 05-14-4.
