Running rich is not good for the engine as it builds up carbon deposits on valves and pistons that destroy the engines performance. Running rich is typical for cold start ups, but quickly ceases once the oxygen sensors warm up because the engine closes the fuel loop and burns fuel to air in the right proportions.
What are the symptoms of a lean fuel mixture?
A lean fuel mixture (too little fuel for the amount of air in the cylinder) can cause an engine to have a surge or miss at idle and part throttle, stumble on acceleration, engine overheating, cause a lack of power, and create possible engine failure from the lean air/fuel mixture.
