I ve been trying to get info on a few things that I want to work on. 1 is the oxygen sensor. I need to replace it, but based on the diagrams of it its connected to the rear exhust area of my car and im wodering if I can do it myself, or are there special tools needed to do it. If not and its possible, what are common problems that people run into in the process of replacing it. 2 is my suspension. im looking at suspension kits, but Im contemplating at some poing soon dropping a higher performance 5 series engine in it. That Being the case Im contemplating going with a sports suspension kit. If its possible I'm wondering which kits would go best with my car. Any I deas???
