5.4 3v rough idle, dies, multiple codes
Just under 3k miles ago I replaced the entire timing system, cam sensors, VVT solonoids, plugs, oil pump, water pump, and one coil on our '06 Expedetion. Changed oil with proper Motocraft oil and filter.
Tonight my Wife calls telling me its running really rough, flashing CEL, and dies at stops. She said it was cutting in/out where it would run fine for a couple minutes then start crapping out again. I'm having it towed home now...
I just happened to have left my code reader in the truck so I have her pull the codes. P0011, P0022, P0171, P0305, and P2198. Looks like a both cams are throwing codes, and an o2 sensor, and misfire on cyl 5.
Am I seriously looking at more cam phaser issues on parts that have less than 3k miles on them? The fact it's throwing both sides seems odd. Not sure what else would cause this considering I replaced every common trouble component on the engine...
She just filled up the tank, maybe bad gas? I didn't change the fuel filter, maybe thats clogged, though not sure why that would cause cam codes. Same with the fuel pump failing, why would that cause cam codes? I just don't believe both phasers crapped at the same time.

well, I saw the milkshake on the filler cap, but the dipstick is clean, though it was a quart low.
Now that I have the truck I can feel it's missing on multiple cylinders, and the CEL starts flashing almost immediately. I cleared the codes listed earlier and messed with it in the driveway for a bit, then rechecked. 5 codes, but now they are all missfire codes, no cam codes. The timing system is quiet as a mouse, no ticks or rattles, or chain slapping at all.
Would a bad o2 cause this?
MAF issue? I can see the PO probed the MAF wires at some point, maybe for this reason.
So, to sum up the night, engine runs really rough, wants to die at idle, flashing CEL, throwing a billion codes that make no sense to me. I didn't have much time to dig into it being dark and 20* tonight. Might be mid week before I can do any more diagnostics.

this might not be your issue but it sounds alot like a bad fuel pump driver module with the running and stalling issues...wouldnt explain the milkshake scenario for sure but some of the symptoms would certainly make sense
