Too many error codes
Driving down the road when our truck went in to limo mode. Originally there were several error codes. I changed the intake manifold, coils, throttle position sensor, cam position sensors. Changed oil. Truck barely starts, runs rough, then dies. Still showing Error codes p2104, 2107, 2110. Any ideas?

Let me make it abundantly clear, codes are a direction not a definite solution towards throwing any parts at the issue, many times additional problems are initiated by the replacements.
It is important you know the correct function and understand how to properly diagnose, guessing is not the way..

seen some of these codes before check wiring harness that run down back of engine on p side and from PCm running to transmission they had a fault on these trucks the holder that hold harness up on back of engine breaks and the harness falls down onto passenger side Exhaust manifold and burns through the harness and shorts out wires to the manifold I have seen this 3 different times on both the 5.4 06 navigator a 05 f150 and a 07 f150 seems to be in the 04 -08 models the transmission control and can bus & O2 Sensors all run down that harness they cause all kinds of hell and limp mode status. pull p side wheel well and look between firewall and back if engine right above the exhaust manifold you will see that harness and if it is laying on manifold. I would start there since I know this can be a issue on them

The "about 12 codes" usually means a fuse is blown. Usually caused by the issue described by bosshog
