Cav. Header
OK i searched but could find the answer. I recently found a cavalier header for slae in me area. I already told him to call it sold so here are my questions. I know it fits fine and everything, but there was the O2 (i think) sensor problem, where you have to get a new port wleded in? If so where does the new spot need to be? Pics would be great. My next question is ive read on here that it makes your computer throw a code regarding to a "low catalyst efficentcy" or somthing. Does this always happen, if so how do you get rid of it?
