Engine bogging?! Need HELP!!!

[yhandor]

Help!!! Whenever I mashed the gas pedal at a light or on the snowy roads here, the engine doesn't rev past 3000-3500 RPMS, instead it starts bogging, like a low grumble, and no power is really being put out, like enough to move the car but when you mash it the tires should spin like crazy in the snow, instead I get a bogging engine, it drives fine on dry pavment and when i hammer it on dry roads, it picks up instantly.....im worried, i dont know what it is, only when its a wet road, a snowy road and rarely on a dry road, it bogs instead of spinning.....someone please help, it worries me a lot....
