1998 Honda Accord 1998 Honda Accord

My car starts normal when it is cold and after driving itfor awhile or soon as the engine heats up, I turn the car off and start it up again and the start is rough starting and at times it takes a few turns of the ignigtion to start and when it do start it start fluttering and about one minute or so it smoothes out and it runs like nothing wronk except when I stop at alight and take off it hesitates only in first gear and the engine seems tobe over heating, I changed the spark plugs and wire and distributor and I still have the problem can you help please.
