I just cleaned my IMRC's and now it idles high-around 1800-2000 before it slowly goes back to 900....it used to get stuck before, but when i would rev it it would go back down....now somehow i made it worse...any idea what i did wrong? Myabe i screwed up the IAC when i cleaned the upper intake? It used to do this before, but nowhere near as bad-only like 1600 rpms, and not all the time, but now its all the time
