MAF

A great investment and a must have.
A Lot of folks are using those high flow air filters like K&N which are great but also present opportunities. The oil in those filters ends up coating the MAF. It's not usually enough to cause a fault code but more than enough to eat away at the MPG. I noticed that after a few months of using a K&N air filter the RPM's at idle went up almost 50 RPM's and my MPG decreased. I cleaned the MAF and that took care of the problem,
Please follow the directions on the can of cleaner and only use MAF cleaner.
