2004 F150 5.4 3v replaced with 2008 5.4 3v
I changed out a Blown 5.4 3v in my 2004 F150 with a 5.4 3v from a 2008 Expedition, Vin5 . Wont idle, cuts out, runs bad unless in limp mode with cam sensor unplugged- P0340 code- wiring, sensor and PCM Check good. Are there Cam or such mechanical changes that could cause this?
Thanks Ahead!

I checked the wiring, ohmed out the pinouts and the sensors, even yanked the intake back off to be sure no pinches etc. bought a new pcm, no change- took to ford and they couldnt figure it out after 3 hours, reprogramming the pcm and even changing the connectors on the cam sensors.
I dont know where to go from here. Suggestions? Points and condensors on my 66 bird is much easier.
Thanks

edit-one other thing-you didn't possibly swap o2 sensor connections and have bank1 plugged into bank 2's harness, and bank 2 plugged into bank 1's harness did you? MAF good and clean?

My suggestions-swap EVERYTHING electrical from the old engine onto the new one. I don't have all the specifics in front of me,but there's something there that the PCM does NOT like. I'll assume that you put new plugs in it?

i will yank off the intake again and change out those sensors and let you know.
Thanks
