CEL on and off
I'm having an issue right now but dont have an obd reader right now so I dont know the codes. Anyways I had a o2 sensor that was out so I had it changed at a mechanic shop. It the upstream sensor. After I got the car back,
Drove it for about a month before I got a CEL again. It stayed on for a week and turned back off. After another two weeks it went on again
And I was going to take it to the dealers today but it didnt turn on even after a 50 mile drive. Ive had problems with o2 sensors for a while. Never before I got my tune. Now that I removed my secondsry cats and resonator, the dealer no longer covers it. So my question is, after putting the new o2 sensors in, is there a way to reset them or do they reset on their own?

I have somewhat the same issue. I have a flaky 02 sensor the will throw a CEL, in fact, just yesterday, went to lunch 15miles away CEL on. Drove home, no CEL. The codes moved to pending/stored when I reviewed the ODBII. The code that caused your CEL should move to stored.
