From the 7.3 TSB regarding oil viscosity and cold weather
94-03 7.3 Idle Lope on Cold Start:
Ford has determined that the engine loping on a cold start is a characteristic of the engine. They are recommending to use a lower viscosity oil--10W-30 meeting API service CH-4 or CI4--to reduce the condition. They also suggest plugging in the block heater when outside temperatures are below 30 degrees and/or waiting up to two minutes with the key on before starting the engine to allow the glow plugs to fully heat the cylinders.
