Interesting, although I spoke with a respected indie, and he says that symptom is not indicative of a maf. His response was, spend weeks trying to figure it out, pay us thousands of dollars to diagnose, or wait until the behavior gets dramatically worse, which it likely will in the future. Basically said consider it a quirk and live with it for now. His initial feeling was a fuel injector. I did just start running 100% gasoline (non-ethanol) 2 tanks ago. Perhaps it has dislodged some gunk in the tank.
