2005 S80 2.5T Engine Vibration

2005 S80 2.5T 58,000 miles. When I first start my car, the steering wheel shudders but is completely fine afterwards - wondering if this is normal.

Also, when driving from start until approximately 40, there is a noticeable vibration coming from what feels like the drivers side floor area. I have replaced the trans torque mount as well as the upper engine mount. I am wondering if I should try changing the spark plugs, or if I should replace the remaining engine mounts.

I also have some low speed clunking which I think is due to the rear sub-frame bushings - I am unsure if the engine vibration could be amplified by this.

Any help is greatly appreciated.

Thanks

Lower right mount maybe bad.

Any codes? A misfire can behave this way. Perhaps a weak ignition coil that's working poorly at low RPM?
