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.
