When i was running my savage out in the snow, i noticed something weird. When i would stop and hit the gas and it would sputter like it was running to lean. I know it wasn't because there was a thick trail of blue smoke coming from the exaust at full throttle! When i would drive it just on the pavement it was fine but when i went in the snow it sputtered. I also have the hpi polished tuned pipe and motor saver air filter.
