Overfilling your car with engine oil is very unadvisable. If the oil is only slightly overfilled the engine will likely not have any problems, but overfilling by more than 1/2 quart or so (depending on the oil capacity of the engine) can result in several problems. The oil will be aerated by the excessive agitation caused by constant contact with the rotating components inside the engine, which can cause engine failures. Also, if drastically overfilled the oil will likely be sucked into the intake system possibly causing "hydrolocking" which will damage the engine. Hydrolocking is unlikely, and since it is relatively simple to remove oil from the engine there is no good reason to operate the engine while over-filled with oil.
The 1997 Acura Integra takes from 4.2 to 4.4 quarts of oil depending on the engine. Check the dipstick to make sure the oil is not overfilled.

It could be that it was overfilled, or it could be that there is a crack in the head gasket that is allowing coolant to enter the oil pan. Or it could simply be condensation in the engine which usually occurs if the car does too many short journeys.
If you overfilled the oil then you can drain some out. There are small hand held pumps that would work fine for the purpose. The exact process would depend on what you overfilled and how much. If the overfill is slight it might not matter on some things and be a big problem in some other. You did not say what you overfilled to give a real exact answer.
