A 6.0 diesel engine may run poorly when cold due to several factors, including issues with the glow plugs, which are essential for preheating the combustion chamber. Additionally, problems with the fuel system, such as fuel gelling or inadequate fuel pressure, can hinder performance in low temperatures. A malfunctioning EGR system or dirty injectors could also contribute to rough running. Regular maintenance and diagnostics can help identify the specific cause.
