Hi, I have a 360 spider 2002. I replace spark plug, valve cover gasket and power steering pump. After all this, the engine run on 4 cylinder's. The only fault code I have is P1571 immobilizer (b1) active in the right engine motronic. I use a autel scan tool. I check all wire, check fuse, the key forb works, the engine start, but run rought. Any idea?
