As the title states, im having temperature and starting problems. basically the truck never gets in the middle of the temp, and so far the starting issue has just started this month. I've change out the thermostats a year ago but the temperature still stayed about the same. what else could it be? im guessing the starting issues is related to p0125 because it also stated something about the Closed Loop Fuel Control? I was thinking it was the Engine coolant sensor? but every time I searched about the p0125 changing the thermostat was always the solution!
