idle control valve & Vac change-over valve
Hello to All, I have a few simple questions
the car is a 1989 420 sel, I was having idle problems & with some help from this site I found my problem to be the idle control valve, so I went to my local U-pull it junk yard and found just what I needed on a 1987 ??? SEL(number badge was missing) the engine was the same from what I can tell, I took the Idle control valve & the vac. change over valve the ICV was made in 2003 the one on my car I think was the original as there was no date on it jus a part no. now heres the question the ICV on my car made this rattle sound when I skake it the one from the junkyard does not, are there any parts in the ICV that could come loose to make it rattle & go bad or is it normal due to the age of the part & what does the ICV really do ? Next question the vac change over valve, The one on my car has a plug wit a screen on it I guess to let air in but the one I got at the yard has a block on the end so no air can get in, & also what does it do in the first place? I looked at pics of the change over valve and the are the same part except for one lets air in and the other does not. thanx for the help
