mine came on last night driving home from work. it came on, stayed on, ran a little rough, i turned it off turned it on again and it stayed on. im way too busy to deal with it so i idled it to the big ovals garage. sounds to me like just an o2 sensor. but whutever it is i have extended warranty on the beast now so it should be covered. tho i may have to pay the $100 deductable.
