Runs rich multiple codes
Truck fuel system is running extremely rich. 5 CO at [url removed] has a large number of codes. Os sensor is new. regulator pressure is 2psi. Map sensor wiring has been repaired previously and could be part of the issue. Is there a way to clear codes on this system? Any help appreciated.
