Default Cylinder 3 Misfire Error Code

I continually have the error code of 3rd cylinder misfire. I have the XLT 4.0 6 cylinder automatic.

I have replaced all plugs 4 times, wires twice, coil pack, and fuel injectors. The mechanic also did some sort of valve cleaning stating I should no longer have the issue (not going there again).

After replacing "whatever" it'll ride nice for about 500 (maybe less) miles before the check engine light comes back on. Then it really "jerks" while accelerating. I'm at a loss, and apparently the mechanics have no clue as they just replace the newly replaced parts. I'm not a mechanic but can follow instruction pretty good. I just need to know if there are any others out there with the same recurring problem and what the fix may be. Thank you in advance. And this is my first post to FRF.

Not to scare you, but my 2010 2.3 was having a missfire code weeks before the head cracked....

Chances are its the infamous cracked head issue well known to the 4 liter Ford motor.

Have your mechanic pressure test the cooling system for leaks and then go from there.
