Tail pipoe smoke on 2004 Volvo S80

My car drives fine but I noticed that when I depressed hard on the accelarator I saw some white smoke from the exhaust. The car was not hot didn't drive any differently then the smoke stopped. I bought it used 104K the fuel pump was just changed from a recall could that cause the smoke problem?

We would have to see the "smoke" to determine if it is normal or not. Get a friend to drive behind you and see if there is smoke as you accelerate of after getting stuck at a traffic light. Are you loosing coolant? Check engine coolant and oil level are at the correct level.
