    May be a vent issue or just a drain line issue, same fix for now. Remove the trap and have a bowl to catch the cup of drain water. Rod into the horizontal line going into the wall with a 1/4" snake. You will hit a 90 elbow a few inches in but just twist and push your way through. Once the rodding is done then reinstall your trap and pour a bucket of very hot water down the drain. If this doesn't do it for you we may be going to the roof to rod the vent stack.
