Typically that means that the computer has detected a condition that needs to be corrected, although the condition typically isn't time critical when THAT light comes on. You can usually wait a couple days, until you can make an appointment with your mechanic or auto dealer. But take care of the problem soon, since it will affect the way the vehicle performs. The "check engine soon" light, is telling you that the computer has detected a signal from one or more of a number of sensors located on the engine or transmission that is not normal. Most times this does not cause a drivability problem, however you should have it checked by a service center as soon as possible, as the problem could cause extensive problems if left unattended, also poor milage.

Would lack of coolant or antifreeze make a car rumble?

It could if you are running it in very cold or very hot weather. In the winter, the engine has to warm the fluids and since the fluids are cold and thick, it takes more engine force to move them. In the summer, they are too thin so the engine isn't fighting the viscosity of the fluids. It's always best to make sure antifreeze/coolant is full. Always check them when the engine is hot. NEVER check Radiator HOT!
