I've delayed asking for help long enough. Car still runs but very badly and rough. Have codes: P0305: Cylinder 5 misfire, P0306: Cylinder 6 misfire, P0308: Cylinder 8 misfire and P1519: which I believe is a runner control stuck closed. Seems odd that I have 3 misfires at the same time. I was thinking maybe an electrical connector came apart partially or completely. The cams are welded and the car ran great, good power, smooth and quiet. Any help is appreciated. My new wife likes the car and I'd like to keep it for a while.
