Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
I am sorry that you have not been helped yet. I just came online and saw your question.
You dont mention any symptoms. Does it idle erratically, poor gas mileage, hard to start.
If your scan tool has live data, let me know what the O2 sensors are doing - staying a steady voltage reading or changing voltage readings constantly
Please remember that I am not there to test it, test drive, or otherwise inspect it and therefore rely on you to provide as much information as possible
