I have been trying to fix this idle problem on my 97 Tib. I have changed almost everything except for the Idle control valve and the fuel filter. I think the idle control valve is working right for the most part because when the car starts to get roudy it ajust the idle to a slightly higher RPM so the car doesn't stall. The only reason I think it might not be working properly is because on a few different occasions the car succeeded in shuting off. Any one got info or a link that might help me out I don't have enough time to search all over the web. I have only searched on here.
