So my CEL came on, I adjusted the gas cap as thats usually the issue but the light stayed on for 3 days. By the time I got it to a code reader, it turned off,literally as i pulled into the driveway So thought all was well and then it came back on today, temp is normal and car seems to be running fine. Although there is a black soot like substance all over my battery and surrounding items. What could be causing this issue? Should I try to not drive my car, seeing as I commute about an hour and a half for school?

As for the radio it will randomly change modes or stations on me, or flat out not work, or make a loud booming noise through my speakers and turn itself off. There are days it works just fine and there is no pattern as far as heat or amount of time driving. Could this just be a fuse issue and/or do I need a whole new deck?
Thanks!

Check the obvious first. Remove that battery and assuming it isn't new, clean it up and take it to Autozone to get checked. A going bad battery can cause a number of odd problems. Pictures are helpful to. Photbucket is free so sign up and show us this black soot.
Disconnecting the battery for a half an hour will also clear codes so when you do get it checked, you won't have intermittent codes from the past stored in there. If your O2 sensor blinked once 6 months ago and is stored on the ECU, do you care? No. Clear them and check for new.
