I have a strange issue with my 08 LX that I am not able to pinpoint. With the fan or a/c running and the (C) button switched 'on' to cut outside air, I can still smell the emission fumes from the front car.

Has anyone faced a similar issue or have some ideas to troubleshoot?

RECIRC mode never completely seals the car off. I have read that it always lets in 10% of fresh air, probably so people don't get sick by leaving it on all the time.

Not sure what the value for the Odyssey is.
