fanufanufan Posted March 24, 2011 Report Share Posted March 24, 2011 there is a part inside the throat where the air comes in - black with a spring - it seems to be part of the fuel injection throat with a micro switch - it seems to control the idle speed - because it brings the idle down - nobody seems to know what this part is - I understand that it was only in the Seville and Eldorado in this year - help - the idle won't go down - I can push this part down in the space which it fits and then the idle goes down - went to the junk yards and couldn't find it - anybody have some insight?

fanufanufan Posted March 24, 2011 Author Report Share Posted March 24, 2011 a little more on this - in this 1977, it is NOT like the TPI (tune port injected) - this one is fuel injection to each cylinder - this part is part of the fuel injection throttle body/throat - anybody know what this part is called? how to identify it to find a replacement? help Link to comment Share on other sites More sharing options...

Texas Jim Posted March 24, 2011 Report Share Posted March 24, 2011 If I am not mistaken... it is called a "FAST IDLE VALVE"...but I have no idea where you can get one. Since your problem is it doesn't go down far enough... i it possible to use some shims on it? If the dealer doesn't have it...maybe ebay?? Link to comment Share on other sites More sharing options...
