Forgot to mention, def not an exhaust leak. I really think lifter from what I've investigated. Could be noisy injector as stated before. I'm not certain if the AFM even works. One time on the freeway, the mpg jumped up to 28.4, but it has not done it again since. At this point I say forget the AFM. I didn't buy the car to get 30mpg. Wonder if the dealer would turn off the AFM without voiding warrany...
