05 fx4 5.4l ignition problem
Hey all just bought this o5 went to go home from work and the truck would not idle right when came to a stop. Then on take off felt like it was not running on all cylinders. I took it back to the dealer and they said that it was mabey a spark plug prob or a wire. I still have'nt got it back yet anyone eles have this problem?

no plug wires on this truck!
did the CEL flash? if not prolly not a plug/COP issue.
Need to ask projectsho if the 05 has an IAC if it does might be the culprit.
Could also be a dirty maf,
vac leak
cam phaser (if equiped)
do a search on "rough idle"
sounds like the dealer you brought it back to wasn't a Ford dealer

I have the same truck as you (F150 fx4 2005) and I had a similar issue today. I was driving down the road and the little orange "wrench" lit up on the dashboard and my truck would not accelerate. I was only a block from a family members house so i pulled in the driveway and shut down the engine. Restarted and everything was back to normal. Drove an hour and a half back home. Don't know what caused that!!!!

An engine misfire. Get your codes read ASAP.
Yes, the 05 still uses an IAC valve. however, when it sticks or otherwise fails, the symptom is usually idle speed problems or stalling/starting problems, not an apparent misfire.
O2 sensors will not cause misfires, either. Misfires are most commonly caused by plugs, COPS, injectors, or other base engine problems.
Your vehicle needs to be checked by a technician that actually understands it. Sounds like this is missing at the "dealership" you purchased it from. Most likely, they don't have someone who is experienced or trained on Ford's EEC system and how it controls the engine.
Try to induce the failure condition, then try to force a CEL. Once the CEL has been lit, get your codes read.
