    Bro you legit just described all my problems god bless I’ve narrowed the high RPM backfires now

    oddly, the RS injectors (100cc more flow than ST injectors) are much cheaper and swap right in...i got all 4 from Rockauto for like $180 shipped. You do need to tune for them since they have a different flow rate (anyone with a FoST generally has a custom tune anyways), but they're a great upgrade too if you have the upgraded HPFP and want a little more fueling to go with the bigger turbo if you've upgraded that also. RS injectors are not much of an upgrade, but its a slight bump to at least support a little more fueling for your tuner to work with.
    Dont forget too that Rockauto ALWAYS has a 5% discount, just search it and apply it to your checkout page. Usually covers taxes or shipping, so its better than nothing!

    Thanks for this video bro, now I know how to replace the injectors on my 14 fusion 2.0EB. 111k miles on the factory ones, think I will eventually replace them with the Xtreme DI injectors as I have gotten an Xtreme DI HPFP. Really need to get my valves walnut blasted too haha

    Hey Nick do you remember what the AFR code you got was? I think I commented a few weeks ago about my own, and I’ve replaced a low pressure fuel sensor and it hasn’t been fixed. I’m looking for pointers as to what I need to do, and I’m dreading that this is the solution. I don’t have an accessport, but I used forscans self test, and it was lean by about .8 on the afr test.

    Looks like blow by due to the o ring seal on your injector being shot on that 4th injector

    Thanks for the video share, I'm on the verge of losing it. I have a 2014 with 87k FBO strat 93 tune.
    Replaced plugs, cleaned intake valves, replaced purge valve, cleaned out my charge pipes, IC, IM, fuel system cleaner, cleaned maf, map, and IM sensor. Serviced my turbosmart BOV, cleaned oily muck from turbo inlet intake side. Installed full OCC and radium pcv plate after thorough cleaning. Recently installed new 02 sensors. Reset ecu learning. ALL THIS AND I'M STILL getting terrible MPG, erratic idle (rpm needle dances up and down until settling) upon cold startup along with misfires (5 to 19 avg). Idle is somewhat rough, have cobb RMM... Hard to tell if it's the injectors causing it. But there is a weird pattern to the idle, not smooth consistency. Kinda of slight up and down but you can't see it in the needle after warm up.
    I def have a boost leak somewhere in the boost selenoid area by the turbo (boost leak tested it and heard it after 12psi, won't hold pass that. Gotta smoke it out. Aside from that I think my injectors are shitty due to the carbon build up I saw in my valves when I cleaned them. I'm hoping once I attack that boost leak and replace fuel injectors, it'll all be over. If not... I might sell. I love the car and this drives me nuts.
    Gonna order the Bosch ones. Good thing I watched your video, I almost did the ship and clean bc i wanted Motorcraft so bad and didn't want to spend $500. So Bosch it is! Thank you.

      Dont forget, there is a fuel rail pressure sensor that can go bad too. its directly under the intake manifold on the passenger side (US models). Its about $60 and mine failed after 3 years of running an E30 tune. You get both low/high pressure codes and misfires once it actually goes out.

    Saw a little trick on restart: turn on ignition w/o starting engine (charges HP pump), turn off...repeat a couple times. It will charge the fuel rail. Ive not done this repair, just a tidbit I noted, cheers.

    Think about this guys. You need a proper fire extinguisher if you're working on the fuel lines. Also, if the car catches fire I hope it's not in the garage that is attached to the house. Because you didn't have a fire extinguisher available, you lose the house.

    Hey nick i am having similar issue at 4500-5000 rpm at wot i start to go lean (14afr) my tuner said my hpfp takes a dip so i replaced hpfp and tappet and still have issue. On the second log he said it might be injectors but my engine only has about 8k miles on it since it was built.

    The heat shield is not a fire hazard, probably there to keep the fuel rail as cool as possible. The real issue you have is that the engine is direct injected. Steer clear of that tech at all costs.

Vacuum hose had to be disconnected to get around wire harness (barb connector broke). Offered the car to a friend for free. He refused. Managed to get $300 from the scrap yard. Never buying a Ford again.
