With the service engine soon light on I suspect it's the thermostat sticking. With this vehicle the engine must reach normal operating temperature of 195 degrees Fahrenheit within nine minutes of a cold start up. If not the service engine soon light will come on and a trouble code will set. Replace the thermostat with a 195 degree Fahrenheit thermostat and bleed the cooling system to insure that there's no air trapped in the cooling system. Hope that helps! Jim
