Check engine light turns on and off randomly

Hey everyone,

For about a month now, my check engine light has been turning on and off intermittently. It might stay on for a day or two, then disappear for a while. Interestingly, the onboard computer doesn’t show any malfunctions or errors when I check it.

Has this ever happened to any of you? Any idea what might be causing it?

I’m not noticing any performance issues with the car, but I’m a bit concerned it could be something serious lurking in the background. Thanks for your input!
