Unless you over oiled your K&N, your MAF and throttle body shouldn't need to be cleaned.

I'd suspect winter blend gas is still being sold in your area or maybe there's more alcohol content (E10).

I didn't know about the fuel filter, that is a bummer. When do they say to bring it in?

Probably got one fill of summer gas then stumbled onto another fill of winter gas.

I was actually at the gas station today and noticed it said 10% ethanol content. I was actually looking because it was mentioned on another forum. would it be worth me getting my tunes redone to accomidate the 10% ethanol mix. I didnt mention it when bill did my tunes. Or does he normally take that into consideration.

I think there was a government mandate that all gasoline had to be at least E10 by a certain year so Bill has been writing them to accommodate for it. Since these engine are low compression, however, there isn't much that needs to be accommodated for.
