Truck Norris status update. I replaced master cylinder, starter, alternator, ignition coil, rotor, distributor, fuel filter and gave it an oil change and dumped the gas.

Break leak is gone! However the truck runs great when you drive it around, but when sitting idle it kind of reminds me of a harley. It's like it's puttering in/out of time and if I don't give it gas, at times it just shuts off. What do you think? Timing belt?
