Welcome and sorry to hear about your multiple issues. It would help to know what kind of Z you have (model and year), together with some background info (mileage, service history, etc). Some problems might be related, but it sounds like you've got multiple problems going on at the same time. For example, P1564 is a steering control switch issue which might occur when the steering lock is removed or damaged. Other codes may indicate some issues with the ECM (engine control module), or the wiring that connects it into the car.
