Sadly I Don't remember the codes, and they are cleared. I did refuel earlier that day with some unknown Station due to being in a far away hill. and there they were no stations except for that one, that clamed he had same 92 octane fuel as one of the suppliers. anyway, that could be the reason maybe? Thanks Weasel, guess I'll have too see again. But that vibration is indeed worying me, so I'm thinking to change those O2s if they throw code again after getting them reset.
