Default SES light on and off?

Did long tubes a month or so ago and since then my SES lights keeps going on and off. using o2 sims but think they are bad. It says slow response from o2, not sure which one.
Anybody else have this?

Get the code(s) read, most likely a front sensor and not the sims, or do you mean it's flashing on and off? Should still be stored in history even if the light is off.

My SES light does the same thing. Ive had it read a couple times and it was a Random Cylinder Misfire code every time so i just stopped taking it to get checked since it will go back out the following day.

If it flashes, then it is not an O2 sensor. Like was mentioned above. It is probably a misfire.
