That's why the lady works at autozone and not a garage.

If you have done all the above, sounds like a problem is IN the cylinder. Like intake valve(S) sticking open. The code is telling you it's a misfire, and your excessive consumption of gas says you have too much fuel going into the cylinder and not being burned properly.

have you check what the code is?? I know you said missfire #3 is that the only code? Is the spark plug cracked? Check the crank sensor, that will give a missfire code as well
