MAF and other odd readings
Hello all. New to the Forum.
I am battling a pitching idle on a 2007 Base Cooper non S, with stalling. My scanner shows the AFR from the MAF sensor fluctuating between 0.75 & 0.77 g/s on a cold engine not running. Also the Absolute Throttle Position constantly bounces between 19.6% and 20% again , engine is cold and off. This is not the behavior I see on our 2011 Cooper S under the same conditions. Possible bad MAF sensor or bad control unit?
