Hello and welcome to just answer and allowing me to assist you. Have you read any trouble codes and what are they? when the engine light comes on the Ecu detects problems in the management systems and will go ito what they call fail safe or limp mode, depending how serious the problem is it will pick an average setting to allow the vehicle to operate in a reduced fashion. If you can get me the codes We can go further. Hope this helps for now and if you require further assistance I;ll be happy to do so.
