its very common on the v6 honda for the idle air control valve to go bad...more than likley it got some carbon in it and it sticking...replace it and u should be fine....this is espically common if u didnt leave the throttle body in the car when u cleaned it...i always leave it in the car...less to take apart and have problems with later

alot of times the air intake sencor gets damaged easy, so check to see if it is working, the car should also have a trouble light coming on, check the code it gives off, that will tell you where the problem is.. Also, sounds like you have a vacaume leak, check you're intake gaskets, check for any rips, tears or holes, this could cause the car to jump around in idle
