Engine dies after warm up and release gas pedal

Question

Concern start after shave engine block
Has new cyl head timing chain with guides and
Tensioner I also replaced the exhaust actuator
Motor and actuator solenoid after warm up engine
Dies every time when I release the gas pedal and
Just before the engine stop sound like if the motor
Or the actuator is loosing oil pressure and doesn't have any malfunction code

Answer 1

Sounds like it more a mechanical problem where the timing is off,installing chain and the camshaft actuator was not fully advanced, would set the timing off., Even if you shave off , this would only cause high NOx. New cylinder head, and it sounds like its loosing oil pressure, you can remove valve cover crank the engine over  and insepct at the cylinder head if the for any internal oil leakage,
