jb4 installed but need help...
Hey guys so back again with another new question.
I searched the forums but couldn't find the answer I needed.. I installed my jb4 on my 335 about 2 weeks ago and at first the car was running strong with no problems. The past couple of days I notice if I am accelerating slow from 1k-3 rpms it stutters ion the way up.. I think it may be the spark plugs.. anybody have any ideas?? and if it is the spark plugs. whats the best brand to buy ?? thanks!!!!! |

If all the connections are good, does your car throw any codes? Have you logged? |

USB/serial cable should be plugged to the JB4 at install time and routed to the glove box for easy access. At that point, you plug it to your laptop, run the JB4 interface and read the codes. plain and simple. if your auto clear is on, then you won;t get any code because the JB4 will auto delete. it's always good to leave it off when debugging. another not so friendly way to read the codes is through your dash and jb4 controls. if you haven't routed the JB4 cable and don;t feel like doing it: http://www.n54tech.com/forums/showthread.php?t=11495 |

At n54tech.com you can find guides which will show and tell you how to read and delete codes and how to log your car. These are the two main things you can do to find a solution to your problem. Or else, taking about it isn't going to give anyone enough information to help.
