Smile Cleaning mass air flow sensor on 2010 v6

My V6 Mustang has 40k on the clock and recently the gas mileage starting going south. Also idle was getting a little rough and acceleration wasn't what it used to be. Saw a video on cleaning the MAF sensor and wanted to share my experience doing this. I picked up a can of CRC MAF sensor cleaner at my local PEP Boys for 8 bucks. I read that when taking out the MAF to clean it that the two torx screws are know to break or strip, I found that it was easiest to just remove the top of the air cleaner box by disconnecting the tube attached to it that runs to it from the throttle body. The sensor can be cleaned while still attached. You can see wires and a red diode looking thing in there. Just spray the MAF cleaner with the little straw attached to can. I used prolly 10 shots or so of spray. The MAF sensor was quite dirty and he cleaner got the wires nice and clean. Also took lose air duct at throttle body and cleaned the throttle body butterfly. It had lots of yellow crud (no doubt pollen) and dirt. Let the MAF sensor and throttle body dry for half hour and put all back together and cranked it up. Ran rough for like a second or so then smoothed out nicely. What a difference this made in gas mileage, idling and pickup. This is a very simple maint procedure that prolly should be done every air filer change or clean. At least once a year I would think. Do not clean it without disconnecting the wires from it and only use MAF cleaner made specifically for this task as using regular carb cleaner of the like May damage the MAF which is a 200 dollar replacement then. Hope this helps and questions or comments welcomed.

Good post, I've been thinking about doing this. My idle gets flaky now and again, and mileage is a bit lower than it should be..

My pleasure. I found it was a lot easier to just remove the filter box housing and clean the MAF sensor while it is still attached. Just be real careful not to let anything touch the wires or anything inside the MAF sensor and let it dry good before plugging it back in and starting your car. I have heard that sometimes doing this will cause a code and the check engine light will come on. If this happens you can either clear the code if you have an OBD tool or just drive it a few times and the computer will take care of it. It's amazing how dirty these things get and it don't take much dirt to throw the sensor off and give false readings. Good luck!!!
