Its also possible that plug or a plug backed out a little. I had an extreme smell of gas after replacing my plugs and even though I swore I tightened them when I re checked them one was loose. the only downside is that I don't know if there is a way to pinpoint a clogged fuel injector other than taking them all out and have them professionally cleaned. I would still check the fpcm under the spare even though it doesn't emit gas smell when its bad. maybe an injector is stuck open

Ford vehicles seem to love Motorcraft parts, that's what I always go with. I am sure you know this but running your tank close to empty is rough on many parts, I try not to run under a quarter tank. You could also run some BG fuel system cleaner through it every once in a while, helps to keep everything clean.

You probably know the fuel cools the pump
Keeping tank filled slows condensation in tank from water in air .
Torque all plugs 25 to 28 foot pounds . The boot is probably shot on that plug .All boots should be replaced when doing plugs .
All new injectors are a good idea at your miles.

So I am digging into this on Sunday, the truck sits until the. I am going to purchase 8 new injectors and install them while I’m at it regardless, if that is th issue or not it’s probably time anyway. Any recommendations on injectors, is it best to go with Motorcraft OEM, and they are the CM5138 correct? I found those new for $33.78 ea on Amazon, does that sound right?

Hi all, first post, I’ve browsed but found nothing really matching my scenario, just looking for ideas on where to start with this so thanks in advance.
2006 5.4L SuperCrew 4x4 with 104,000 miles. Truck has been running perfectly, within last 6 months have had all plugs changed, pssanger side manifold, and full fuel system clean done by Ford dealer. Also replaced air and fuel filter.
So so while running late for a work meeting the other morning I ran it nearly dry on fuel, to the point of stumbling into the gas station after my meeting. On startup after filling the tank it was running rough at idle, on the drive home it still was running rough at low rpm, but seemed to clear up under load and at higher rpm. Nearly home the check engine came on, too it to Autozone for code read and came back with P0172, P0300, and P0301. I looked them up and found they are system too rich bank 1, misfire cylinder 1, and random misfire.
I put put in some Royale Purple fuel system cleaner thinking that running low on fuel maybe picked up some crud from the bottom of the tank and drove it for a short while. Starting up this morning it started hard (3-5 seconds), blackish smoke and strong fuel smell. Same rough idle seeming to clear under load.
Could a stuck open fuel injector cause this, or more than one? Is that likely the issue, crud from the bottom of the tank? What about a fuel pump problem, I’ve seen these returnless line models have fuel press regulated buy voltage to the pump, if the pump overheated could it be stuck on full pressure? I will have time for more diagnosis this weekend, but this is where I’m at now, looking for ideas from experience, thanks!
If there are mistakes blame my phone.

They were delivered today, got to love Amazon one day shipping. Sure enough, OEM Motorcraft brand new in sealed packaging. They go in tomorrow, hopefully that does it.
