An LT1 engine may stall once warmed up due to several factors, such as a failing fuel pump, clogged fuel filter, or issues with the fuel injectors that affect fuel delivery. Additionally, problems with the ignition system, such as a faulty ignition coil or spark plugs, can lead to misfires and stalling. Vacuum leaks or a malfunctioning idle air control valve can also disrupt the air-fuel mixture, causing the engine to stall at idle when warm. Finally, issues with the engine’s sensors, like the coolant temperature sensor, may provide incorrect readings, affecting engine performance.
