2014 Ford F-150 CEL after air filter discovered backwards

I have the 2014 F150 STX 5.0 liter. I was driving home after an oil change and my truck lost power and I had it towed home. Found the air filter was install the wrong way. This caused the air filter box cover to not seal. I put the air filter and cover on the correct way and the truck runs good with no driving issues. But know I have an engine light on and am getting a P0430 code. I changed my spark plugs, both downstream O2 sensors, and fuel pump. Anyone who can share info on this? I would really appreciate it. Thank you.

Have someone connect a scanner to monitor the signal from the O2 sensor.

If the converter is bad, it’s warranted for 8 years/80,000 miles by the manufacturer.
