Dear Anybody: I purchased a beautiful 1990 420 SEL yesterday that has been sitting for awhile. It idles alittle rough at times and after driving it for about an hour in city i noticed a slight fuel smell which does dissipate, the previous owner said it does need an idle sensor relay- is this what is causing the fuel smell? thanks for any help- Siduri http://www.peachparts.com/shopforum/images/smilies/confused.gif
