If you have the procede check your wg setting if its at 90 try lowering it to 50. I had this problem ended up replacing water pump and thermostat and it didnt solve the issue. Come to find out it was an issue with the tune. Changed that setting and all was resolved. If not it could be the coolant sensor. If not then go for the other 2 items last as they are a fortune out of pocket.
