If you are trying to clean your throttle body, leave it on the intake manifold. Just spray some O2 sensor friendly intake cleaner in it while opening the butterfly plate. Once it stops pouring black out of it, put the intake hose back on and start your car and let it run for a few minutes. It will probably spew black smoke for a bit, but its getting all the junk out.
