use throttle body cleaner (not carb cleaner) and spray the throttle body with the engine running. also it doesnt hurt to wipe the insie of the tubes...
to clean the IAC, remove it from the throttle body and just use the same throttle body cleaner...also helps to have a few q-tps or junk rags to wipe it out in the inside...

does the rattle come in under load like climbing a steep hill?
also i recommened everyone try Seafoam. it'll clean out the top end of the engine, mostly the carbon build up on the valves and intake passages. runs about $5 a can and u put it in slowly through the brake booster vacuum line with the engine running. be sure to pour a small amount in at a time so the engine doesnt die.
use 1/3 to 1/2 a can and let the motor off for about 20 minutes. then start it up and hold it to about 1500-2000 rpm until the exhaust doesnt smoke. repeat and proceed to change the oil.
most people noticed a difference with this and some others havent.
make sure to change the oil after and do it where people dont mind being smoked out :)
