sounds fuel or oil related.
how long since you changed the oil?
i had a shake at idle before as well, i rebuilt the Fuel pressure regulator and it helped some.
i the replaced the icp and that helped more.
also i run synthetic oil and the truck runs smoother.
on a random note you can try a different cps.
i recommend the delphi hts101. little smoother starts and idle over the ford grey cps.
why do you need to plug your truck in? mine starts fine in the teens unplugged.
