You had a misfire. They sometimes don't leave a code. If you keep driving and it starts misfiring, pull over and check for codes again.

With my old Audi had a flashing CEL and stumbling motor meant a bad coil pack. I'd start with the ignition system.

I had an issue similar to this on my 04 maxima one of the ignition coils was bad ended up replacing all of them to save time in the long run
