i noticed when i run my car to normal temp (right on the left hand side of temp icon) after a few minutes it will drop down to the halfway point between completely cold and the icon. it will hesitate while in D4 but when i kick it down the hesitation disappears until i release and let it upshift. i have also been noticing steam coming from my radiator area...not a lot but noticable. no clear indication of any leaks...however i saw that it was low by maybe a few ounces or so. not enough to use a gallon up in even a few months time. my heater works fine all the time...well once its warmed up. any ideas? thermostat? radiator issues? temp sensor? head gasket? no check engine light or service light. i have had it almost stall on me over this summer with same symptoms but without the radiator steam. id hate to let this pass by and risk an engine by being forced to use just water while on the road and have the block freeze up on me. any help would be greatly appreciated. thanks. have a merry christmas everyone here at honda-acura!!
