Well, this may be it, the last failure. P0301... Blown rings/motor

I am so confused. This car makes no sense ... all three bank1 injectors are leaking. how? ... all at one time INSTANTLY?? makes zero sense. compression test came out fine.. injector test hard failed on 1,3 and 5 was meh.
I give up on trying to understand ... done-zo..baffled...utterly baffled...

Just curious, how many miles are you at? And do you do any regular fuel system cleaning?
After my stuck injector (around 34k miles maybe?), I ran 2 stroke oil in every tank for 2 years (probably close to 40k miles). Never had a repeat, but stopped with the mix because it was too much of a pain for my wife when we swapped vehicles. I just ran a bottle of Amsoil PI through the last tank. Don’t really notice a difference but hoped it might keep the injectors clean. Kinda paranoid now after first failure around 34k miles. Still not sure if the stuff is snake oil or what, but it makes me feel like I’m doing something preventative.

ETA: Disregard the rest of my reply below. Didn’t realize you were 2010, so this probably doesn’t apply to you. Sorry, man.

FWIW, you may want to consider checking your warranty guide (download available online). The fuel injectors may be covered under the 8 year / 80k mile “Emissions Performance Warranty”.
I was out of standard warranty (due to time), but the Emissions Warranty covered my injector replacement.
They said they were only authorized to replace the one injector in my case, but if you failed half of them, maybe they will replace them all. Definitely worth asking!
Also, if you’re not already at a Ford dealer, and you’re inside the emissions performance warranty period, make sure you save the bad parts...

Have to wonder if that had more to do with your plug fouling than the plug themselves. I have not heard of anyone else having issues with colder plugs, I know I have not and I live farther north than you do by a few hundred miles. Could be the fouling was a warning sign of the failing injectors that only showed as an issue when you put colder plugs in?
I agree with SHOdded, make sure they replace them ALL. I had a buddy up here when I 1st got my SHO. he had one go, replaced it, then couple months later another failed. screwed the car up pretty good both times and cost him lot of money having it fixed and torn apart 2x.

I don't have all my records in front of me for exact mileage, but I bought my XSport used (3 years old) with 28k miles. I swapped out what I assumed to be the OEM plugs at ~30k when I put in my tune. OEM plugs looked good, no signs of fouling, and were replaced with one step colder NGK at the advise of Torrie. I went through a tune with Torrie, then Brad, and had my #2 injector fail at around 34k miles. Only about 4k on the brand new plugs. #2 plug still looked great, other than being wet with fuel. I assumed mine was a random failure. The dealer would only replace the failed unit (under warranty), so I'm still running the original injectors on the other 5 cylinders (45k miles later and no issues... knock on wood), but I think SHOdded indicated earlier that a lot of these failures tend to occur on Bank 1? Makes me wonder if something else is just inherently wonky with the design or assembly process with bank 1 injectors.
Maybe having 3 injectors fail at once could be due to excessive fouling? Regardless, it certainly seems to be a freak failure to have all three go at the same time with no prior warning. I just wonder if it's too much of a stretch to try and compare this to the more "typical" single stuck injector that is seen more commonly?
I wholeheartedly Agree with SHOdded and the Rear Bank 1 is where the Heat soak accumulates.Pics of the Hood for reference below. Z
I wonder if any is related to the Pulse Width Modulated (PWM) & (PCM)
Fuel is metered directly into each combustion chamber.Fuel injectors pulse to follow engine firing order,in accordance with engine demand.
PCM controls the opening duration (Pulse width) of the Fuel injectors and maintain optimum exhaust emission control and engine performance for all operating conditions.
