Haven't been here in a while because you all helped me resolve any past issues..but now I have another unfortunately. My check engine light came on a few days ago so I ran it by Auto Zone to see if they could get a code on it. It came back with "the ECM has detected a fault with the downstream 02 sensor. Probable cause..check other service codes first...next it says check leak near 02 sensor..then failed 02 sensor..and lastly it says fuel contamination. So I took it to our mechanic and after having it for several day with the last being today because he said he need the car to be cold to do whatever he was going to do. He called to say that there is nothing wrong with the car and he thinks that maybe something or other needs to be recalibrated or updated and I need to take it to a dealer who is capable of doing that. So..I'm coming to the place where I know I will get great advice and I thank you in advance!
