2010 Ford F150 – Making a diesel sounding noise mostly at random when slowing down or stopping. Comes out of it when giving it gas. Have replaced both Cam phasers, 1 timing solenoid and one coil pack. Originally we thought it was the Cam phasers cause its that same noise but after replacing we aren’t sure. No codes come up when it does it. No check engine light. Anyone have a thought??

 

I'm moving this to a forum where you should get more help. Also, what engine do you have?
