Accepted Answer

hi if its really the sensor that keeps going bad it will be that the car is constantly running lean causing the 02 sensor to lean out to much and overheat and go bad, if this problem is not resolved than it will continue to do it., you need to find out why is running so lean,maybe fuel pump, fuel filter, vacuum leak ?perform a fuel pressure test see if its ok,replace the fuel filter and see what hipping's
