The black plastic thing in the throttle position sensor , does the obvious , tells the ecu how far up it you have your foot etc .
Without a pic its hard to say as there are two different 16v manifolds but on mine you loosely describe the air idle valve . Its like a choke , alows more air in etc so the ecu gives more fuel and a higher idle , it comes on on things like a/c on etc .
Thats not explained to well , anyway sounds like its stuck open . I expect it will run ok with it off but you may find it stalls out here and there when it would normally open .
