well, DUH!! the other day, the CEL came on in my wife's Subaru. it was alarming to say the least since we were far from home. car seemed to run fine.

when i got home, i took the time to think about "what has changed?". it hit me. i changed the engine air cleaner because everything up here has been sucking in sooty smokey air. (filter was black!). i neglected to close up the airbox tightly, and inadvertently left a corner unclipped.

i hooked it all down correctly, double checked, triple checked..and disconnected the battery. upon start up..no CEL!

that it? done?

how does an aftermarket cold air intake not trip the CEL? i was shocked a tiny bit of air whizzing past the element would trigger the CEL.
