alrighty guys so........98 LX civic. we have replaced 2 ignition switches in the last month. and i also replaced the stock cat with a ebay header (was cracked all the way around, so got a cheap fix) and the second 02 sensor wouldnt fit in the bung so we left it out. My buddy said i wouldnt have probles leaving it out. But my wife was driving it around and it randomly decided to sound like it was straight piped?! i didnt believe her but the mother ****er is LOUD. and it also boggs BAD from a dead stop. Is it cuz of the o2 sensor? I just bought one and imma take it to the exhaust shop and get the bung moved and put the new sensor in. Hopefully that fixes it so i can sell the thing to get our GTI lol. Only codes is the 02 sensor......But im kinda puzzled. Thanks guys.
