My check engine light has been on and off for a few weeks now so I had the dealership check it out. Apparently its a problem with the "1/2 o2 sensor voltage high." I declined the service at the time since I was already dropping 300 for the tune up!!!!!!! Has anyone else experienced this problem or know the seriousness of it? Hopefully it won't be too costly!!! Happy holidays everyone!
