Multiple codes
I got a 2006 ford expedition 5.4L. I have been getting codes p0316 p0357 and p0430. I feel like it might be the catalytic converter on bank 2 or a failing coil on bank 2. Has anyone else had any problems like this?

Resolve the most critical issue of the electrical circuit fault on cylinder 7's coil (P0357) first. The P0316 is probably due to that cylinder's misfiring. The P0430 is probably a damaged converter on bank 2, likely due to excessive fuel dumped from cylinder 7's misfiring for an extended period of time.
