I have a 1987 chevy r10 with a 350. When the engine is cold it will stumble when trying to accelerate. It idles smooth and its not missing. Only stumbles when trying to accelerate. feels like an ignition issue. Once the truck gets up to operating temperature, it runs perfectly. Just replaced pickup coil and ignition module trying to fix it, but the issue is still the same. Other things that have been recently replaced are coolant temp switch, fuel filter, fuel pump.
