Sick ls
 

I'm having problems with my 57 chevy truck fuel injected 6.0 350 trans. Upon start up high idle then it levels off. When I'm coming to a stop it tries to go dead or will. Runs fine in park no problems. Drives on road Good but those 2 major problems to me. Any thoughts for me

With a 350 turbo I'm going to guess you dont have a VSS hooked up? Not having one can cause the stalling problem you describe. As for the idle, they usually do that, unless its extreme in your case, check for a vacuum leak.
