Hi guys My 2007 BF XR6 Turbo sedan is running rough ever since removing the battery to replace a drivers side light bulb (headlight). And also it has brought on the traction control light on dash, but when I go to turn it off it won't turn off. It was idling rough and felt like surges.It also stalled once. Drives fine on motorway but once changing down gears and putting into neutral it starts to surge and slowly corrects itself.
