Scotty! Thank you for what you do! I live in Columbia TN so right away I would like to know how to get set up with you as a customer! Now onto my car question!
2003 F150 5.4 triton. Auto trans and 326k miles on original motor and transmission. Problem started out with a misfire. Turned out to be a bad coil over. Replaced it and the check engine light came back on. Fixed the misfire but now has code P0175 rich bank 2. I replaced the MAF sensor and reset the code and it came back, same code. Since rich bank 2 can be a host of issues, what do you suggest first? Once again I would love to get in contact with you somehow to be a costumer of yours too! Thanks!

Problem started out with a misfire. Turned out to be a bad coil over.
A coil over is a suspension component and extremely unlikely to cause misfire. I think you mean an ignition coil-on-plug.
Replaced the coil and the check engine light came back on ... I replaced the MAF sensor and reset the code and it came back
This is the problem with the parts cannon approach instead of diagnosing. You've thrown a bunch of money at the problem, it's still not fixed, and you have no idea what is causing it.
