Default CEL on 00 2.5 RS

yesterday i took my factory intake off, removed oem air filter and put in a K&n panel filter. i put everything back together and left it. then at night i went to a friends house and as soon as i started the car the cel starts blinking. car ran fine, i didnt drive hard, just took it easy and everything was fine. today i took out the k&n and put in the oem filter again, thinking the cel would go away, it didnt. i tried the ecu reset method of disconnecting the battery, pumping brake pedal, then reconnecting the battery and idle for 10 minutes. the light is still blinking. anything else i can do?
thanks
curtis

A flashing CEL indicates a real-time misfire. If it started after installing the K&N, there may have been too much oil on the filter and the MAF got contaminated (I think you have a MAF on your car but not 100% certain). Should that be the case you would have to remove the MAF and clean it (using MAF cleaner only).
It's also possible that you disturbed or disconnected something while installing the filter, so take a good look around under the hood for any loose hoses or connections.
Finally, did you for any reason plug the green connectors together under the dash? Doing so will result in a constantly flashing CEL (among other things), if you did this go unplug them ASAP.

Check to make sure you actually connected the filter box on the bottom. It's kind of hard to see down there and easy to screw up putting it back on securely.

connected the filter box tabs or connected the filter box itself to the throttle body?
i removed everything and inspected, i had accidently unplugged one small hose, so i plugged it in. disconnected the battery, waited, hooked it up again, started it, and its idling now, but the cel is still flashing.

i decided to check these under the dash, and in fact they were plugged in. i got the car like 2 weeks ago so the previous owner must have plugged them in. what are they for anyways? do they need to be plugged together again?
it solved the flashing cel regardless. thanks for the tip

The plugs are for putting the car into a diagnostic mode that is used by the dealer, and for pre-delivery. Some re-flashers such as the Accesport also use them. Other than that they need to be left unplugged.
It's odd that you believe they were plugged in since you got the car, as the light would have been flashing that entire time. Did your friend or someone else have access to your car while you were working on the filter, and could they possibly have connected the plugs?

really no way you can drive 2 weeks with them plugged in, the cel will always be flashing and the cooling fans running off and on. You must have a ghost.
