Idle Problems??

[BigBronco187]

Whats up guys? I have asome questions. I just got my bronco back from the shop about a week ago. It runs and drives fine, but when i let it sit (warming up or at a stop light) it shakes. BNot alot, but i can feel the rear end of my truck give a weird back and forth shake every about 10 seconds. It last for about 2 or 3 seconds and stops. Any ideas?

By the way its a 95 if you needed to know that

well start with your fuel filter it may be clogged then check yoour air filter it may be all gunked up and limiting the air to your engine if those are good check your plugs, wires, and the cap and rotor they might have a bit of corrosion lowering your spark also check your oil cuz if its old and has alot of grime in it your straner picking up the oil could be a litle clogged but thats worst case sinareo so check it out and let us know if that dosent help /
