Well I ordered a new Catalytic Converter since I think it's going bad "Smells". I ordered the Magnaflow Universal which should be here tomorrow. Has anyone used a Universal one before? Will it work? I took the exhaust off today to get the new one welded on and when I took of the Oxygen sensors and this is what they look like.[IMG][/IMG]
The top one was replaced around 6 months ago since I have a check engine light and the scanner stated it was the front o2 sensor and that did not fix the problem :(. The bottom one is the rear sensor that I have never changed. Is that Black build up normal? Should it be replaced?
