The check engine light came on and I finally wanted to get things fixed due to a new relocation to a state that does vehicle inspections. I had the code read and it showed the O2 sensor is bad. I did research about this and the dealer price was too high. I checked numerous online sites and finally found all four sensors from different locations. I bought them and waited for their arrival. Upon their delivery I did them myself and after 4 hours and lots of scratches and sore back I was done. Reconnected the battery and no light ...YAY! 2 days later, light came on and I was told to have the ECU Cleared. Did that and 2 days later ...Light came on...GRRR
