I have a random CEL that has come on and off a few times and gone off on its own. I felt a mild skip the last time it came on . My my mpg is around 16.3 to 16.7 sometimes I'm getting better than that on average. No issues filling up and fuel going in. Capless fuel nozzle seems to be fine no debris or anything..ive read some saying this fix is pretty much 2 parts but ford has told.some they need a new pcm and that didn't fix the issue. This is a 2019 I just turned over 100k on it. I have the service records and oasis report. The only.issue that I've been concerned with is it failed emissions , dealer took it back 3 days later it passed. I test drive it and it throws CEL for P0420 P0430. Dealer took it and had it for a few days and those codes never came back, no CATS were replaced or O2 sensors but that CEL has never came back. I know the P0420 and P0430 are emissions also and this is another emissions CEL so I'm wondering what is going on. The resonator has been deleted but the rest of the truck is 100% stock.
