cool, mine definately rattles so hopefully i am heading down the right path in fixing this dicky idle. I am running out of things to replace to rectify this as well as money. I have replaced, 2 new fuel pumps, injectors, dist cap+ rotor, alternator, recond head and guides etc. I have only owned it 6 months and it des have a elatively new battery, perhaps the old one died and someone jump started it and blew the OVP?
