My 2006 Sts has a very rough idle and then while driving

What is your question?

It straightens out while driving for a short distance then goes right back to riding rough. Replaced fuel injection harness and coding #4 injector. Even replaced the 4 and coil and plugs and valve body.

How long has your 2006 Cadillac STS had this problem?
