anyone know what the cause of a sporadic puff of smoke upon startup...Everytime that ive noticed it its been white..Which I always thought was a head gasket or something like that, but the smell is similar to that of a tractor when it first starts...Thats the best way i can describe it...Any help is greatly appreciated...Also ive been getting an intermitten check engine light with very rough idle but everytime I check for codes nothign comes up???
any help with this would also be greatly appreciated...Thank you
