2013 Silverado Emission
Hello, friends,
I own a 2013 Chevy 2500 with the 6.0 liter flex fuel motor. It has 156,000 miles on it.
Over the course of the past two months I have replaced the plugs, coils, wires, three cats, four O2 sensors, map sensor, throttle body, all filters and oil. I run only Chevron or Shell gas in the truck. Every other tank I add a bottle of Sea-Foam. I am getting ready to replace the injectors, fuel rails, and gas cap. I cleared all codes and drove the truck for 100 miles. It ran superbly. However, the computer is not recognizing the new cats so I am blowing O2 codes. Everything I install is AC Delco. Can any of you suggest what I should do next to fix this issue?
