I went down and had a smog guy do a quick sniffer test to see where my 83sc motor is at and here are the results! What do they mean? The guy at the station said I had an exhaust leak but other than that the numbers were good! He couldn't tell me what that ment, lean or rich or good, probably because he was a test only guy and knows nothing??? (IMG:style_emoticons/default/confused24.gif)
