Hello my name is Jake i am new to the site and hoping for some help. For starters i have a 2004 Fx4 with the 5.4. Under load i am getting what seems to be a misfire. When i pull the codes i get P2106 and P2006. It seems like it is going into limp home mode. Under my ABS codes its showing that none of my speed sensors are comunicating and my ABS module is faulty.

What ive done so far-
New throttle body, with new TPS sensor
New MAF
New Throttle by wire set up
New IMRC Actuator
New spark plugs and checked all coils
New ABS module (from salvage yard)
PCM reflashed and ABS module reflashed to match PCM

Same codes continue to pop up and truck has loss of power and stumbles. Any help would be greatly appreciated!

 

You haven't checked/cleaned/replaced any of the ABS sensors?

 

Actually no i havent. I cant imagine every speed sensor would go bad and it would throw a ABS module fault code.
