My check engine light came on a few days ago. It's throwing high voltage on both O2 sensors. We had 4" of snow followed by 12" a few days later. So the car had not been driven in roughly ten days. I've searched the web but haven't really found a definitive cause for this. Just wondering if anyone else has experienced this. The car runs a little rough until it's warmed up. A couple times I was cruising steadily along and the car takes off like it's got more power all of the sudden. I've logged a couple drives to see my o2 sensor voltage is running and the short term fuel trim but honestly don't know too much on the subject. Any ideas as to what could be causing this? Thanks
