Hi all,

A quick question about my recently acquired landbarge ('84 300sd). At idle, especially while conld, it shakes pretty significantly. While cold, the airfilter housing rattles all over in the engine bay, and while sitting at a red light, it is enough to shake the entire car noticeable. Is this normal? I do have to adjust the valves (I don't know when it was done last, currently 111k miles). Could I have some sort of misfire?

Thanks,
Jack
