Default Shaking Engine

Driving my 99XJ classic with 250,000km the yesterday on the highway when I started to get a knocking in the floorboard on the driver's side.
When I shut it off, the whole engine gave a good shake. Does the same thing when I start it up. It was a little sluggish going up hills as well.
Any suggestions would be appreciated.

D. Not enough information.

Vague guess... I'd say it's misfiring severely. Or was way overheated.

Check your motor mounts, either the rubber or the mount to engine bolts can fail.

Thanks guys. Took a look at the motor mounts and the rubber is crumbling away. That is definitely a part of it.
