Installed the air filter but no luck. I'm at 14mpg. I took out and cleaned my vanos solenoids today and noticed something....when my car was parked and I revved the engine, it would rev nice and smooth but when I let go of the gas pedal the needle came down normally except around 1200rpms it feels like the engine hiccups. Tried it a few times and everytime there was a "bump" around 1200rpms when the needle was coming down.
