well today it was unusually nice out so i had to take the z out for a drive. i ran a couple errands and noticed that after the car got to normal heat it was idling abit hight, around 1500-2000rpm. any clues as to what this may be the only mods i have on the car are listed below.

i will check in the morning as long as the weather permits, supposed to get cold and snow tomorrow. i can say i dont think it is a vacum leak, because it did not do it at start up, only after the engine warmed up. anyhow jow do i check the tps and iac valve?
