things to do first (if not done already)

First thing that I would do is give the car a very thorough tuneup. Those figures indicate an excessively rich mixture. Pull the plugs, replace them, new wires, change oil, replace air filter, check PCV valve. Check engine light on? A defective 02 sensor can also cause an excessively rich condition. I would check the cheap stuff before buying the expensive stuff.
