at a loss. help.
So over the weekend I was working on my girlfriends car changing the valve cover gasket, all went well. She drove it for a bout an hour then the dash dimmed out and the radio turned off and sure enough the car died and wont start without a jump. What's confusing me is that after I jump it and it warms up it does the same thing. It's been sputtering lately off and on and a few days ago threw a cyl 4 misfire code. I checked for oil on the plugs since i had that issue before and sure enough there was, so i changed the valve gasket, didn't touch anything else on the car. It's an 01 se. Any help would be appreciated. Thanks
