My check engine light is on and my jeep will shake when I first start my car up. on 2001 Jeep Grand Cherokee

Usually it will shake when I first back up, but it will stop once I accelerate and start driving. However, this morning the check engine light started blinking and the shaking continued as I drove. Any advice?
