I need a little backup.  I have a 2001 outback wagon, one of the first things that i did to it was to switch the paper  element air filter to a K&N filter.  About a month later the CEL came on, took it to the dealer and it was the engine idle control code, they told me that when i put the air cleaner box back together i didn't seat it correctly into the bottom tabs (not good for the ego).  But then a week later the CEL came back on, the new story is that the K&N filter is drawing too much air and causing a lean condition.  BS i think.  Anyone had a problem with this code and could it be related to the air filter?
