It's probably missing... fouled plug, or otherwise
bad cap, rotor, secondary wire. Do a tuneup...
save the plugs in the order they came out, so
you know which went where... hell, your Haynes
has a decent chapter on this.
If it *still* misses, then look at injectors... pull
the injector wires one at a time until you find
the one that doesn't change the idle... there
you go.

Re: engine idle vibration
How is the clutch on the fan?
Is the serpentine belt wearing ok? If it is getting any wear on one
edge, suspect the harmonic balancer.
