Hi mech5107 That is really a good idea about the idle control valve! Can this be found on most Toyota engines? I took my car for diagnostics and troubleshooting,when I got it back an apprentice gorilla had crushed the unit in a vice ( guess he thought a girl would not notice and said he tried to service it and it really is not a  necessary item......) The car had a slight misfire and  high idle, when I got it back it was undrivable .(maybe his mate needed some parts????.) Am I correct in thinking that any idle up solenoid will work even if it looks different? Is it meant to
