Q: Impala rumbles upon cylinder deactivation

KimberlyMy 2008 Chevy Impala makes a rumble sound or vibration when going from 6-cylinder mode to 3-cylinder mode, with or without slight acceleration. It sounds fine when it goes back into 6-cylinder mode. I am concerned. Any suggestions?

Is this one of those rare occasions where "replace your spark plugs & wires" actually makes sense
