silvermace 0 Report post Posted January 17, 2009 So i was in repco looking for some leather care products and came across "CRC Mass Air Flow Sensor Cleaner" thought I would give it a go because my idle can sometimes be tad rough and I doubt theres such a thing as an overly clean MAF Was really easy to do, got the Haynes E46 guide out, whipped off the air box and MAF housing+sensor, gave it a good 10-15 sprays (as the instructions say) and let it dry off over a few minutes, the reinstalled. Took about 15 minutes, and did notice a bit of oil/grime build up on the 2 ultrathin MAF sensing wires dissapeared. Car's idle is now at 750rpm or 1100 rpm, rock solid. and a very noticable difference with throttle response especially in 2nd. Attached a pic of the can for those keen to give it a go.
