Hi guy's working things out preaty good here the only trhing that I have to figure out now is why my 96 Sentra is so cold blooded? I believe that there must be a boarder line problem with my fuel inrichment on start up?? Is there a cold start sensor? If so what is the value of this senso supposed to be? I have no codes on it but If it is startring to get out of wack could this be causing my problem? Or is there somthing else to check?
