The B2468 Code is explanation of the car problem. Do not use the general meaning of the code for solving the car engine problem. While fuel economy was increased, acceleration was seriously compromised, and the loss of engine vacuum led to a dangerous loss of braking assist when the B2468 code system was in four-cylinder mode. In addition to these issues, while the company proposed a hydraulically controlled system that could be substituted from within the car, the version they applied had to be manually different in the engine section using hand tools. Do not drive the car with the engine problem.
