89 Civic automatic with 220,000 miles on it. I usually drive this car before the warmed engine. I don't like to sit there and wait for the engine to get warm. I don't mean I don't idle at all. I do idle about 3 or 4 mins. I have some noises issue under driving with not-warmed engine such squeak when I hit the break and some kind of whistling or whirring sound I don't know exactly where it comes from, but once the car reaches normal temp, these noises disappear. Also the car seems to run a bit of overloaded on driving with not-warmed engine . Once the engines gets norm temp, the overloaded feel gets disapper.
My guess on these noises.
Squeaking break = Master Cylinder is not fully operated under not-warmed engine Whistle or Whirring = I don't no idea.
