Q: Glow Plug coil lights up while driving.

asked by on

its a Van cargo, glow plug light is flashing, it looses or reduces speed. The brake lights both come on

Hi there. The controller to the glow plugs is malfunctioning and tripping the ECM (computer) and telling it that the engine has stalled. I recommend replacing the glow plug controller / timer unit. If you need further assistance with your glow plug circuits, then seek out a professional, such as one from Your Mechanic, to help you.
