The buzzing is the frequency valve running-should run constantly. Check to make sure the large vacuum hose (not the small lines) on the back right (passenger) side of the intake is connected. Should be clamped on there so it doesn't leak. Also make sure all your spark wires are seated and connecting with the spark plug, sometimes they're on but just not "on" and making contact. I'd say you have a large vacuum leak somewhere or a bad spark wire connection is your problem. -----Dani B. #5003 To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
