u1900 code
once In a while on start up when I accelerate hard the motor misses and the ck engine light flashes. as soon as I let off the gas the miss goes away and the light goes off . I cant get this to duplicate any other time other then start up and not always all the time. recently it missed so bad that the ck engine light stayed on and when I checked the codes it was a general misfire, no specific cylinder, and code u1900 Can Bus failure or communication error. this "mechanic" buddy of mine erased everything on me because he said it would cause performance loss and reset the light.he said I needed to get a computer reflashed but im not sure, any ideas? Thanks Joe
