I have a 1960 f-100 automatic,I just recently put in a rebuilt 292 v8 because I burnt the crank in the old one. Everything seems to run well except I have had trouble with the idol. Had an intake leak but I think I got it . The trouble I am having is when I step on the brakes and come to a stop it wants to die,also the idol is smooth but tend to fluctuate. Do I have an intake leak still or am I missing something else? Help???? Thend19
