My vote goes to the 1)spark plugs 2)coils 3)TPS 4)maf. The uneven idle points to coils or spark plugs more often than anything else. You can easily check all of these if you search for the procedures under the 4th gen sticky's.

Check your tps but DO NOT LOOSEN THE BOLTS. That's only b/c I have gone through a headache for about a year now. I unbolted my TPS when i didn't even know what it was. I thought it would be a good idea to clean the inside of that thingy attatched to the intake. Wrong.

I drove on the interstate for about an hour w/it fine. Then on the ride home my car would surge but under 0% throttle. I was set at cruise at 70 and it would jump around. Even when i thought i had it calibrated correctly i would get surges when set cruise on the highway (TPS warmed up). You have to have your tps sensor warm to get an accurate reading in Ohms. Check the sticky's for a good writeup...
