219B Engine Code Help!
Hello group 👋
new member here, I have a 2013 Silverado 1500 with the 5.3 in it that is giving me a 219B code. I’ve looked it up and found that it is a fuel/air imbalance but can’t pin the cause down. I’ve replaced upper and lower O2 sensors and it came back on. I took it to the dealer and they couldn’t find anything..
please help, I have an emissions test coming up in July 😳
