Just a "check engine" light. Probably a bad sensor somewhere. That's an emission control situation. If you are using an aftermarket "tune" or chip, that can throw a code.

It's weird that he says the problem is worse but doesn't say anything about what the problem is. Is it just a CEL or is there actually a problem that he feels while driving the car? So little information in that video.
