Hello All

I have been getting lots of smoke from the engine exhaust. checked with Hawkeye showed no real related problems. I checked the MAF sensor located near the air filter. did not seem to be faulty when checking the output frequency on the Hawkeye. I cleaned the sensor with a MAF cleaner ( be careful about using strong solvents in the sensor) allow to dry refitted. went for a test drive MPG around 35 no smoke Etc. This sensor will not show a problem if dirty. the system uses the incorrect output and supplies fuel as it think is needed. If you are having similar problems try to clean it first, I had the EGR valve in bits ( awkward to remove and fit ) before I got to this point. Lesson learnt. the sensors are expensive so as said use caution when cleaning and the correct cleaner. Most motor factors should stock it.

Haven't had to do a MAF on the FL but did on the Jag I had - used Maplins electrical cleaner - aerosol can costs about £6 from memory and dissolves the crud off the sensor wire and blows it away at the same time. DO NOT brush the wire No Longer the owner of a 2013MY Fuji White GS
