(More) Grammatically Correct Version:
I have a 2014 Ford Fusion with the 1.5 Ecoboost engine. A couple months ago it began misfiring in cylinder 4. I changed the coil pack spark plugs and it still kept misfiring. Then, I took it to the Ford dealer and they changed the injector and it still misfired. They told me somewhere I got bad gasoline and it would need all new fuel lines, injecters, and a fuel pump, so they did those. After all the work, it still misfireed so they tore the engine apart and said the piston in cylinder #4 had a hole. Apparently I needed a new engine and I don't understand (neither does anybody else I talked to) why bad gas would cause a hole in the piston. So I'm curious if anyone else ever had this happen or did I just get scammed by the dealer?
A couple of things:
1. FYI, here's a list of problems recorded for the 2014 Fusion by carcomplaints.com

2. Maybe it's time to get a second opinion. The dealership is NOT usually the best place. Given what you've said, they've thrown a lot of parts (aka "the parts cannon") WITHOUT ADEQUATELY DIAGNOSING THE VEHICLE.
3. Yes, if everything you've said is true, then the dealer scammed you, a combination of greed and shop incompetence. (It's hard to know which element was more dominant).
Here's a tip: Find a shop specializing in DIAGNOSIS, not mercantile sales. Pay for the diagnosis. If they can fix it, get a iron-clad and enforceable guarantee that the problem has been fixed.
4. Don't ever go to a dealership for out-of-warranty service.
Good luck to you.
Have you talked with your mechanic about it?
