2006 Toyota Tundra SR5 4.7L MIL Lamp on
I have a 4.7 tundra with rich codes. Smoked the system and no leaks. Both up stream sensors are at 3.25 volt and will change with load. The rear 02 sensors are at .85 and stay there. If i create a vacuum leak the fronts will go to 4.2 then come back to 3.2...
