Well - those are all misfire codes (cylinders 4 and 5) and engine misfire detected on startup (First 1000 Revolutions) (P0316).

There is a specific troubleshooting technique for misfires and simply throwing parts at the problem will not fix it. It could be the coils (but probably not since they already replaced them), could be the plugs (did they even look at them?), or it could be a wiring issue. Have they swapped the 'bad coils' with other good coils? Did the misfire follow the bad coils?

I hope you purchased this at a Ford dealer and hope you know the warranty is 36 years or 36,000 miles.

Don't let them simply 'reset' the computer. All they're trying to do is get you out the door. Keep at them and if necessary 1) take it to another dealer or 2) get your money back.
