akirby Posted September 2, 2014 Report Share Posted September 2, 2014 Is it malfunctioning? Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted September 2, 2014 Report Share Posted September 2, 2014 There's no set interval for MAF cleaning/check. If you want to be preventive, since you are running a K&N, maybe do it every 30,000 miles (normal filter change interval)? Definitely do it shortly AFTER you clean/oil the K&N just in case any excess gets stuck on there. IMHO. Quote Link to comment Share on other sites More sharing options...

akirby Posted September 2, 2014 Report Share Posted September 2, 2014 no its not. Personally I wouldn't mess with it unless there is a problem. It's a pretty sensitive part. Quote Link to comment Share on other sites More sharing options...
Bryan003 Posted September 2, 2014 Author Report Share Posted September 2, 2014 I cleaned it and my idle is about 200rpm lower throttle response is better and i noticed a little differance in mpg. Quote Link to comment Share on other sites More sharing options...
akirby Posted September 2, 2014 Report Share Posted September 2, 2014 So it was malfunctioning, just not enough to be obvious. Quote Link to comment Share on other sites More sharing options...

akirby Posted September 2, 2014 Report Share Posted September 2, 2014 I wonder if that explains some folks who are having problems and/or poor fuel economy. Quote Link to comment Share on other sites More sharing options...

sixponies Posted September 3, 2014 Report Share Posted September 3, 2014 As long as you only use MAF cleaner on it, you can clean it as often as you so desire. Last night, I changed my oil/filter, cleaned the MAF sensor, and cleaned the throttle body. Throttle response seemed a little better this morning on the way to work. I'm going on a road trip this weekend, so hopefully I'll see a bit of an improvement in MPG. Of course, that's largely dependent on the weight of my right foot!
