Can you define "wasn't that dirty" and describe how you cleaned it?
I will tell you this-I can't count the number of rigs I've cured this issue on after folks have told me the exact same thing...
To clean properly, you MUST remove everything, and scrub every nook and cranny with a tooth brush thoroughly using a good TB cleaner. Exercise the plunger on the IAC and scrub it too, along with opening the throttle plate and removing the haze around the ring. You want a mirror finish here on all of it-if you don't have that, it isn't clean enough. Absolutely no haze or dark color of any kind-if you have that, it isn't clean enough and it will lead to rough idle and surge conditions. Sorry, not that I don't trust your cleaning job, but I've been told that more times than I can count and it wasn't clean enough which lead to the same issues you have here.
How many miles on the rig and is it totally stock? You don't have one of those screwy jet chips or anything like that do you? No TB spacers or other gimmicks?
Stick with factory plugs as well-regular NGKs are hard to beat.
Best of Luck,
