Yesterday, while driving on the highway at 100 kph in cruise control, I noticed on MHD that the AFRs which I was monitoring would begin fluctuating for a while and then come good. I took a datalog which I will attach. At the same time the AFRs are fluctuating so is the throttle position. The rpm doesn't alter at all. Has anyone got any ideas on what could be the cause for this?
