Hi,

I recently bought 2 K&N Replacement airfilters-1 (33-2135) for my Av an one for my wife's 03 Mountaineer. After putting it in the Mountaineer, I then unhooked the battery so the computer (ECU?) would optimize itself for the currnet condition of the truck (i.e new filter). In fact, the trip computer show an astounding 5 MPG better if you can belive that. In the Av manual, I saw no such sequence or mention of it. Did I miss something or does the AV do it automatically. In the past, I owned an Acura an I belive when I changed that filter I had to reset the computer.
