Coil went out on vacation 700 mls from home. I was able to do this myself but found very stringent requirements for wire routing and plug wire sheilding was necessary to prevent crossfire. Found info online to route exactly as specified and replace all wire sheilding looms as they are stock. Big pain in the rear since this area is difficult to reach. Had it not been for all the warnings of crossfire I would have routed them differently to avoid tight areas.
