I have a 1998 kia sephia ls with 96,000 miles. I have replaced the O2 sensors, pulse generator and the vehicle speed sensor and doing so cleared all the codes. The vehicle runs great and doesn't overheat. After the last code of vehicle running too lean I replaced the O2 sensors and the codes all cleared. While driving it the check engine light came back on but vehicle still runs great but when I ran read the check engine light there are no codes. Any suggestions?
