I need some help, since I've swaped out my H-pipe my computer is not getting the right air/fuel ratio from the O2"s and its been smoking when I take off from a light , Its just a cloud of smoke and then its fine, it just does it after sitting at idle for a min. or 2 and it smells real rich. I've tried unplugging the postive batt. terminal to reset the computer and it works for a while (about a day) and then it starts again. Am i doin something wrong? I even put mil eliminaters on the rear sensors. Well thanks for any advice. ???
