also....last sunday i filled my car with shell 93 and drove around 130 miles on the highway just that day, it was a little above 3/4 tank. Then the past 3 days i noticed this and i have put 120 city miles since monday before filling up again today.
So say if i replace the O2 do u think i still need to replace the cat? Its two weeks old and i hear the heat shield rattle alittle. Let me know thanks
