I have a 300text that will just about kill the battery when it's chilly out, even worse when it snows or gets below 60. I have to pump the gas to start it then very gently ease on the petal or it will immediately stall out the idle nearly shakes the whole car. Once it's ran for 5 minutes it's fine acceleration there it won't stall out no matter how hard you stomp it, it will idle fine very consistan. I planed on changing the csv but can't find it. Any help appreciated
