OKAY!!!!! try this, sit in a garage or something inclosed and not seeing cold air... rev up to 3 and hold and see if temp gauge stays at that point or keeps going up..... if it goes up your thermostat is bad (replace it fast or else your overheating) if it stays the same then your radiator is taking in too much cold air (Like Mine is right now). and when you drive does the temp go down? cuz mine does that cuz my radiator is getting so cold that its like my engine has never been started up. so find out if thats it.
