I was driving my 2024 F-150 XLT (V8 engine) the other day and decided to aggressively accelerate to beat a "yellow" light... (Yes, it was yellow :teehee:). After passing the intersection, I noticed my check engine light started to flash for approximately 10 seconds and turned off. I have not been able to duplicate the issue since and no codes are showing via the OBDII port. I was going to take it to the dealership, but then I figured why, especially since I have been unable to reproduce and no codes. I did a search of the forum, but did not notice any situations like mine (unless I missed it). Has this happened to anyone else?

Usually a flashing cel is a misfire. Hopefully it was just a one time thing.

Yes... Thank you. Forgot to add that information in my original message. I did google the issue and spoke to a couple mechanic friends of mine. They said the same thing.

Flashing CELs need to be checked ASAP. It indicates a misfire.

Checked how? What will the dealer do if there are no codes stored and they can't replicate it?
