[blageo23]

Thanks! Maybe some more info would be good too. Just in case there might be somehting else. its a 1998 BMW 323IS, 95000 miles, 2.5 straight 6, The O2 i mentioned was the first one. The secound O2 comes up .6-.96 and like 60%. In what Ive heard is the "normal" range. Again what does the % mean? Thanks for the info Rick!
