MY CHECK engine light is on and it sounds like its only running on 5 or 4 cylinders! instead of 6. the code is. egnition coil primary/secondary B circuit malfunction, idk , and no shop can figure it out!! its really annoying ! how can noone know what it is ?? and if i keep my engine running for a lilttle while the injector fuse will burn out . and then it wont start at all. but if i replace the fuse it will run really bad and no power!! , then later the fuse will burn out again!! .
