Hi Scotty. I am trying to figure out why my 2005 ford Taurus has a rough idle when its warmed up. If I rev it to 1200 rpms in park it runs extra rough as well. I've already tried cleaning the throttle body as well as the IAC with carb cleaner and its still doing the same thing. Could be plugs and wires but that's a bit of a hassle and I've read many things that can cause a rough idea. Any ideas?
