O2 and VSS codes
I checked the wiring and all 4 are O2 are OEM. Came on again but came off as soon as i filled up with 91 octane. The wife put in thencheap stuff while I was gone. Could Cali's bull crap winter blend fuel also be meesing it up if it started to clog a injector.- jwhowes

O2 and VSS codes
Codes for both N2 upstream O2 sensor and VSS sensor just came on. Its only intermittent and when its cold in the morning. All 4 sensors are brand new and just passed Cali smog. There is no issues otherwise. Runs fine and no change to idle or anything. Plus like i said it resets by the afternoon...- jwhowes
