ok when i started my car about 3 weeks ago i noticed my car was idiling erratically when i drove and even when i put it into neutral. it sounded like i had a bad batch of gas but i wasnt sure. When it kept doing it i checked my spark plugs just in case they were bad.....i checked my spark plug closest to the back and the cap was very loose and i pulled it up and it was covered in oil! i'm praying its not my head and was wondering what else it could be.....like a gasket or something.....i also want to know the costs of repairs...:1zhelp:
