Flashing CEL

Hey,

so today, not the first time, after a bit of harder driving(going all the way to 5500rpm on all gears from 2nd to 4th) and then easing off, I got flashing CEL. After a while it stopped, just before I pulled over and stopped the car. I let the engine run for a while, jumped into trunk and took my OBDII reader, which had shown 0 errors.

Turned off the engine, let it cool for a while, started the engine and drove for a while normally, then pushed it again, nothing happened this time, no CEL.

This is the second time it happened, first time I noticed it was on highway, where I wasnt even pushing it too hard.

Any ideas what could this be? Maybe failing lambda or catalyst, which couldnt comply with the amount of air going through and didnt filter the CO2 contents properly?

Edit: Google search shows something with running rich and that it may be caused by Blowoff valve that I have? Any confirmation on this?
