I suggest you take your vehicle to a qualified technician. The are many things that can cause an engine to shake at idle. Let's start with the basics. Since your vehicle is 13 years old, a valve job may be in order. Check spark plugs and ignition wires. Perform a compression test. A cylinder with 10% or more differential in compression will idle rough, but at higher engine speeds appear to be ok. Also, injectors and vacuum leaks must be taken into consideration.
