Hey members: I have a 2006 Mazda 3 and after the engine runs for a couple of minutes and I am driving above 25 mph the temp gauge goes almost to the Hot section. The ac starts putting out warm air but, if I let up on the throttle and let the car coast the temp gauge immmediately begins to return to normal. Then when I begin to accelerate the temp gauge starts going toward the hot. This is the 4 cyl and in the morning the heater is not hot it is just warm air, but the gauge shows almost hot. When i slow down the ac starts working properly. No check engine light has come on. Any ideas will be greatly appreciated. Thanks
