ok so I installed the FocusSport CAI and drove around for about 3 hours with no CEL, now today I pick it up from the place I got my windows tinted and the CEL is on. Checked under the hood, all seems ok, disconnected the battery, CEL is still on. Figured this is probably normal but if you look, in my hand I am holding a rubber hose that was connected to the stock intake. On the FocusSport intake there is no spot to connect this... No air comes in or out of this when you rev the engine. Is this normal or could this be the source of the CEL?
also when I start the car it makes a grinding whiny noise, goes away after a few minutes, but happens again when i turn off the car... is that normal too?
ps it's a D20E... that's the PZEV
