Been having performance isseus, loss of power, slight throttle hesitation, low idle or at times the engine will shut off while idling when I first start it up, plus the MPGs are killin me lol. My best guess would be the snapped off Coolant Temp Sensor just hanging loosely in the engine bay, any helpful tips or advice to the easiest way of removing the metal threaded part of the sensor still in the Head? Wanted some input before I started taking things apart to get to it.
