Ok so here in atlanta it finally dropped below freezing and well the car is sick. I am having problems starting the car, it sounds like there was an arcing on the battery so i tightened the terminals..ok seemed fine but then driving the battery light on the dash came partially on, sometimes more than others and then sometimes lighter and going away. The manual says its the generator belt is loose, which is the main serp belt which I checked and seemed ok and I find it hard to believe it is loose. So what other suggestions do you guys have / experience, I'm kinda paranoid now that the battery may not be charging fully and I'll end up with a dead battery, but the car runs fine w/ heat on and headlights radio the works, and seems like the batt light gets lighter when I'm running more stuff. Any suggestions?

Also I still have not replaced my knock sensor A6: 1-4-3 yet but have ONLY run on premium and reset the computer every time the CHECK ENGINE light comes on. Would this electrical issues have anything related, I know it sounds silly but hey its a brick who knows.
