Sorry about being a little slow about this response. Many of the replies hit it on the head. The belt was one tooth off. A nick on the rear cover was mistaken for the actual timing mark. Retimed the rear cam and now all is well. Trouble codes: P0300 (Random Misfire), P0301 (Misfire Cylinder 1), P0303 (Misfire Cylinder 3), P0305 (Misfire Cylinder 5).
