2007 Kia Rio SX 1.6L MIL Lamp on VIN: KNADE12307
P0304: Misfire cylinder 4. Came in with P0304 and P0456. The engine was not misfiring when we checked it but every 10 to 15 seconds you could hear a spark arc sound. After looking all around we found an arc jumping from the balancer to the oil pan. Any ideas?
