I have a 1999 Mitsubishi Eclipse. It is running very badly. At times it runs fine but others will barely stay running. I just had the code read at Autozone and it said the Up stream oxygen sensor and miss in cylinders 2 and 3. My question is can a bad oxygen sensor actually make the car run this badly. Do you think replacing it will take care of things?
