My check engine light is coming on when I use my heater.
When I turn on my heater the temperature drops and my check engine light comes on. I turn off the heat and let the car idle and the light turns off, but the temp goes up to about 175 degrees. I'll drive the car and the temperature will drop and then I will park it and the problem seems to go away. What would cause this?
Is dit een goede vraag?
