The meaning of the B2344 Code is necessary to get from the original source. The dictionary meaning of the code is not a real source. You should get the meaning from the manufacturer. The car manufacturer set the real meaning of the code based on the model of the car. The B2344 engine code seems a kind of body problem. While fuel economy was raised, the acceleration of the engine was very compromised, and the loss of engine vacuum led to a hazardous loss of braking backing when the B2344 code system was in 4 cylinder mode. Solving the car engine problem is very easy.
