I got the tip from MattMainster. Go to your local FRY's electronics or the like and pick up a can of PureTronics contact cleaner. dont make a mistake and buy the compressed air duster, it need to be electronic contact cleaner. This is mostly for those with a CAI. the oil and dust will build up on your MAF and kill your gas mialage. It only takes a flathead screwdriver and a can of this stuff. spray liberally onto the matchtip looking probe as well as up into the hollow sides of the sensor. I was getting 13 MPG hwy, now I'm up to 15 and i got alot of weight and fat tires. probably better for those with less mods.
