I have a 2004 with the same symptoms and checked/replaced similar parts. I also adjusted the valves. No change. I assumed it was a mount as it feels a mount that is “bound up.” It is a slight vibration, at idol, under load only. Once under way the vehicle is smooth.
I have this feeling some other part (power steering hose?) may be transmitting engine vibration. Now that the weather in Michigan is getting better, I am going to do a deeper dive into this issue. If anyone else has ideas…please share!
