I have observed that the AFR on my car has changed the last days. Earlier that the WB show a AFR of 13-15 under normal load. Now the AFR value is 17-18 (max). What could cause this? Clogged injectors or some other things. Unfortunately I don´t get any DTC and with such high AFR should I get a DTC for lean bank 1 or 2 or both? I Have attached a short logg file. Is there some one who know what I should look for.

ps I have also observed that the fans runs more often. ds
