Thanks for the response...I really do not think it is the cats after more investigation. The car has had the distibutors modified to work with one set of points, instead of the two point system...the distributors have not been set-up on a distributor machine? How important is that? It has been recommended to me to put both sets of points in the distributors and dial them in on a machine. There is also a throttle switch that controls their action (as I understand it), I am not certain what effect this switch has with only one point set per distributor? I think it is best to set it up in the original manner? The Ferrari mechanic that is recommending this procedure has offered to set-up and sync both distributors and assures me that this will remedy the problem? If anyone has ideas or can confirm this thinking it would be helpful...Thanks
