I have a f150 2018 2.7 with code p0430 p0420 but my concern is p0471 & p0299 also showed truck doesn't run as powerful as before power when passing a car on the highway before i buy both catalytic. does a bad catalytic causes these codes to pop up?
- I also changed exhaust pressure sensor egr tube and thats when this code pop up the p0471 and p0299
Have you looked up the potential causes of those codes (P0420 and P0430 are the same for different engine banks)?

It end up being the catlytic converters. Replaced both all codes clear drove 60miles no return of the codes.
@j0j0 Yikes, that's pretty tough and also unexpected on a vehicle that new. Thanks for letting us know.
