The intake camshaft on bank 1 is more retarded than commanded by the ECM. This reduces engine performance and efficiency. Often related to oil viscosity issues or a failing VVT actuator.
The exhaust camshaft on bank 1 is more advanced than the ECM expects. Usually caused by sludged oil blocking the VVT actuator or a stuck solenoid.
