How can you tell if an engine is running lean or rich?
Too rich and you will get black smoke from exhaust. You can also read the spark plugs. way too rich and the engine will bog down or flood out in extreme situations. If it's running too lean, the rpms will get erratic.
What does engine running rich or lean mean?
An engine runs by the combustion of a mixture of oxygen and gasoline. If this mix has too much oxygen, it is said to run lean. When the mixture has too much gasoline in relation to oxygen, it is running rich.

That code is telling you that bank two is running too lean. For some reason the fuel mixture is too lean. Possibly an o2 sensor is malfunctioning.
1984 x.f.have done a full service on it leads plugs coil carby kit has a problem it sometimes cuts out while driving it will start again then go ok for a while and then do it again any ideas please?
Just wondering. When does it cut out? You arn't running it too lean. The car will struggle up high revs if it's set too lean. Just an idea. Just wondering. When does it cut out? You arn't running it too lean. The car will struggle up high revs if it's set too lean. Just an idea.
Your 2000 ford windstar check engine light is on and the code reads running too lean - what does that mean?
Running lean basically means that your Air Fuel Ratio is off and there is more air than fuel, which creates a lean condition. It is called the "Stoichiometric" value. The correct ratio is 14.7 parts air to one part fuel. If you are running for instance a ratio of 16 to 1 then that is lean. Basically too much air when compared to optimal air fuel mix. A ratio of 12 to 1 is too rich. The problem with a lean condition is that the engine will run hot. Normal logic would suggest that with less fuel there would be less heat generated, but it is not the case. A lean condition will actually make the engine run hotter.

Just had this problem. I replaced the oxygen sensor and it appears to be running fine.
