Knock Sensor Code and Rough Idle

Hey folks, having trouble with my 04 TL. Thankfully nothing as nerve racking as before, however:

The car throws the knock sensor code even though the engine isn't knocking and we've replaced the knock sensor itself. Also, when driving the car runs fine, but when stopped at a light or anything, it idles roughly.

Could these 2 be linked? Any suggestions? Thanks in advance for help.

thats rough one man. Not even sure where to start.
First things would be to diagnose the issue. Just because it threw the knock sensor code, doesnt meant that the knock sensor was the issue. What was the code number?

Ever have the fuel injection system professionally cleaned?
Have the valves ever been adjusted?

Which brand(s) of gas are you using?
