I put headers and an a kat back exhaust on a 98 civic lx (automatic trans) in an attempt to make the car a little quicker. The problems started once I realized that the stock kat was conected to the old header , so I had to get a staight pipe ( kat eliminator ). Also, the bottom o2 sensors was stuck so we were advised to cut the wires and sodered them to the top sensor wires. This works for a while, but the check engine light eventually gets thrown. So now, my question to you fine people is : what should I do? If I buy a new o2 sensor for the straight pipe will this satisfy the computer in the car and keep the check engine light off. Or will it not matter with the o2 level reading since there's no kat? Please help , I can't just keep disconnecting the neg wire on the battery for ever ( to reset the light ) or can I. Thanks
