First suggestion is a good tune-up by replacing spark plugs, air filter, cleaning the throttle body, and an oil change.

Beyond that you may be looking at a failing O2 sensor - most likely the front one.

Slight leakage from the rear muffler should have no emissions effect, but could be a safety item (carbon monoxide getting into the cabin).
