The New Coil is in

Well, I replaced the coil today. I'm not sure if it was my problem or not. As I was working on it, the hose that goes to the pressure retard unit was so loose, it fell right off. I'm wondering if the lack of any kind of seal would cause my misfiring. The pressure is come right behind the turbo so if if there is not a good seal, that would be gas blowing out of the hose. It could also explain my huge knocking problem. If there was in fact no seal, there was no pressure to retard the timing cause the spark detonation when I boost. Its a theory at least.
