You're getting old enough to suspect the anti-siphon valves under your sinks. You can get them at Lowe's. I'm not exactly sure what they are called but just tell them you want the devices that vent drain pipes and prevent siphoning the traps dry. The rubber flapper in these get stiff and/or dirty and fail to seal. I had a similar problem with my 2000 Magna and replaced 3 of them. Two were under the bathroom sink and one under the kitchen sink.
