Leo190,

Yes, just disconnect the hose and carefully wedge it out of the way of the entrance to the throttle body. You do all this cleaning with the engine off. It might be best to have a second person inside the car holding the gas pedal to the floor so that the butterfly valve will be open (horizontal). Have the other person alternately press the gas pedal to the floor and then release it a few times so you see how the butterfly works. Then, have that person hold it to the floor so the butterfly is fully open so you can easily clean it. I actually use my fingers to clean the backside of the butterfly and the area around where it seats inside the throttle body. Just spread the cleaner around with your fingers. This leaves no residue from a rag or broken bristles from a toothbrush. Put the car all back together and start it up; it may be difficult to start but it eventually will. It may run rough and idle rough for a few minutes and it will exhibit some black smoke at first, but take it for a ride for about 5-10 minutes and it will all smooth out. Your car should also idle a bit smoother after this treatment.
