was driving my savage 25 in the snow a few days ago. my friends were throwing snow at the savage and hitting it when it went by them with snow and they were throwing it around in the snow. the radio equipment has not worked right since then and i have dried it all. the truck takes off with out me hitting the gas and it changes to reverse when im driving it. the truck also will no turn good and it will not go very fast. please help me. it only does this when the engine is running
