I just had my ECM replaced and leaving the service center my car shook and then turned off. Also I had smokey exhaust most of my drive home. Has anyone else experienced this? Is this normal?

Nope you have a problem. I suggest you take it back and get them to have a look. The learning process is only minor trimming and would make no difference in the driving.
