Is running lean too much fuel?
Your engine runs lean if your air-to-fuel mixture is too light – this means that the fuel in your ignition chamber is being igniting with too much air or too little fuel. Your engine running lean is always a symptom of another problem – it could be a dirty MAF sensor, a damaged oxygen sensor, or damaged fuel injectors.
What happens when you put lean fuel in your car?
A lean fuel mixture affects the combustion process resulting in a significant loss in engine power. Loss of engine power reduces acceleration, especially when going up higher grounds. When you turn the key in the ignition, the engine may completely refuse to start or only start after several attempts.
What does fuel cut mean on a car?
Fuel cut is actually a removal of the the injector firing signal from the ECU. This is to say that your engine computer doesn’t put fuel in the engine, hence the name.
What should fuel trim correction be for lean running engine?

What happens when the fuel supply is so lean?
When the engine fuel supply is so lean that combustion can’t even occur, the engine dies out and stops working. In comparison to seizing, this lean-running danger is actually better because the operator can quickly put the vehicle in neutral before the engine stalls completely.
