Generally speaking when a car stalls out going uphill, a few things come to a mechanical mind. 1. Going uphill produces a strain on the engine and drive components, if you have the old points and coil type vehicle one could suspect a faulty ignition coil as the culprit. 2. A vehicle on an incline may be low on fuel and thus stalls on a hill because it is starving for fuel on this incline. 3. A faulty float inside the float bowl of your carburetor may be the problem.
why does my 1991 Chevy lumina that when going up a hill or when it reaches approximatly 65 mph starts hestitating, when cars get older they do that.
You can do some engine mods, but the simplest way is to drive it better. If you're turning 3.36s with a 12.8 engine, it is what it is.. you're not going to make much of a hill truck out of it.
