I have the SS model. I have been getting o2 sensor error codes. Anywhere from eight to eighteen codes, upstream and downstream codes, Low voltage, Lean codes, rich codes. I would type all the different codes but, it would make little difference. Pretty much every code out there I keep getting. I have spent a small fortune having the dealership try and fix it. I have replaced the following items. Upstream/downstream sensors, banks 1 and 2. Mass air flow sensor, High performance GM spark plugs and wires. I have the codes reset. After a day or two or sometimes the same day, They just keep coming back. Bottom line, I have spent way too much money as a lab experiment at the GM dealership.
My car symptoms are horrible fuel economy, at slow speeds sputters before shifting. (I have an automatic transmission).
I am looking any help you can give me. I do not know where to take my car. Please, Help me!
have the same problem?
