I'm looking for any help in diagnosing a lean code banks 1 and 2. Truck has 95k on it. any help would be sweet. Thanks in advance.

 

Head Gasket. Happened on my Chevy, recently ( I only have one Chevy and it's just for hauling firewood). New gasket and sealed the manifold. Fixed the problem. Could definitely be the same issue on any V8. At least you have codes to let you know it's running lean without having to pull all the plugs. Good luck.
