completeley and uttereley stumped!!

ok here is the deal, when my car has been sitting for a while it runs perfect for about 15 minutes but after that its runs really crappy kinda misfiring, stuttering when i get on it basically just not running to its full potential, here is all the things i have replaced, all o2 sensors, wires, plugs,cap and rotor, and thats about it , what else could this be? it bugging the hell outta me , btw no ses light, and its not cause of the temp cause my car runs cool since i installed the manual fan switch
