Lincoln LS 2003 3.9V8, P0357

I have a 2003 Lincoln LS. It's showing Code P0357. So during that I found the valve cover gaskets where bad so I changed them put new spark plugs and a new number seven Coil pack. The computer was reset and it still feels like it's missing but the only code is P0357... have any ideas what it could be?

Thanks for using my website. Here is something that you can try:

Swap this coil out with another that's easy to get to and clear the code (you might have to take it to an auto parts store to have the codes cleared and read again). Restart the engine and see if the code switches to the new location of the coil or if it stays put. A new code means the coil itself is bad. If it stays on cylinder #7 (P0357), the control circuit is the cause.

I hope this has helped.
