Running rich

• Oxygen Sensors-If malfunctioning they will not read the correct mixture of air/fuel in the exhaust, causing the engine to supply more fuel into less air. These generally, but not always throw a code. Most commonly these are just replaced since they are not expensive or generally hard. You can change the sensor from a four wires to a single, and save some money, this is explained here… http://forums.probetalk.com/showthread.php?t=1701054184

Or you can replace it with a four-wire sensor, explained here…

Rough ride

• Shocks-This is generally the problem, the shocks control how much bounce or play is in a ride. The bouncier it is, the smoother the ride but lacking in handling generally. Replacing these with firmer aftermarket set will give the vehicle more control in cornering and wheel motion. Many aftermarket units allow the adjustment of the comfort level. This allows you to choose whether you would like a rock hard ride, or a soft smooth ride
