HOT-FILM AIR FLOW METER, LH BANK

 

This is an old thread but I thought I would light it up. I have a 2001 360 and the idle is fluctuating after it warms up. I am getting the P1104 code on my OBD scanner as well. If I unplug one or both of the 2 MAF sensors it idles well. If I plug both back in, it idles rough, like from 900 RPM to 1300 and everywhere in between. Anyone know how to fix this or what’s the culprit other than both MAF sensors?

 

Did you tried to clean the AFM's?

 

Yes I cleaned the AMF (Mass Air Flow Sensors) with CRC brand Mass Air Flow Sensor cleaner. Then I was advised by 2 mechanics to never clean them, they will go out when they go out and cleaning them speeds the process? I also cleaned the plugs, contactors, with CRC electrical contact cleaner. Anyway, I am 99% sure I have one or two bad Mass Air Flow Sensors? The part number on the Bosch MAF's is the same part number on a Land Rover and Honda Accord model. The Ferrari MAF is $250.00 and the Honda or Land Rover is $50.00, but has to be ordered in.
