So within the last month or so it really seems as if I am getting much worse gas mileage than I had been. (I have taken into account that it is winter and cold here, but its been cold now for much longer than a month) I also noticed that when the rpms drop to idle... they go well below idle (it seems like close to the point the car will die) before leveling out. I just switched out the pcv valve, as well as put in a new air filter. Anyone had similar problems or have any ideas? Thank you in advance.

Check spark plug gap (or just replace spark plugs with new and properly gapped ones), check IAC valve, may need cleaning. Also do idle relearn procedure after above steps. HTH
