recently a user meddled with the metering of my AFM. as a result of this, my fuel economy suffers quite badly. is there any way the diagnostics can tell if it is operating rich or lean or optimum. I don't like this experimentation. so, how can I set it back to the original setting?
the AFM is one for e36m42 engine, but installed on e30 4 door.
thank you.
