I am not having any luck with responses and I have done my research - please someone help me out

some reason AMMCO will not do anything to my truck and so I have to take ti to Ford - my huge issue is that when I drove it there the 4WD would not engage. After they "looked into it" they said the Edge tuner is causing the problems - I asked if they took anything apart and they did. But after I paid $190 to get it back to take it some where else

NOW after they took things apart - it drives very sluggish - I mean 25 mph with the speed showing 100MPH ...with no power -

they gave me a list of codes

P061B - Internal control module torque calculation performance

P2004 - Intake runner control stuck open B1

P2105 TAC system-forced engine shutdown

before I took it to them only issue I had was 4WD not kicking in and a humming noise at 50 to 60 MPH -

can someone please help me figure out what is going on .

 

I believe the P2004 and P2105 is the same I codes I had come up, I'm getting the throttle body cleaned. Mine was going into Failsafe Mode.

 

these people at AMMCO are idiots! they have on there that one of the codes was C1729 T/Case unable to transition 4 H-Low!!! ARE U KIDDING ME - but whould that cause a issue for bogging and driving sluggish all the sudden?
