I have attached a video. Engine idling rough. I have replaced the timing components, camshaft sensors and solenoids. Replaced Engine Oil and Filter. Replaced Idler Control Valve.

It sounds like there is an issue with the valve train, I would remove the valve cover and inspect the roller flowers and camshaft lobes. Thanks for the video. On the second video I could not see much though? Were you trying to show the codes? If so, can you list them in your response, here is how to remove the valve cover. It could be a worn-out camshaft actuator as well. Please go over this guide:

Yep, these numbers act like there is an issue with the engine. I would also do a compression test to see if the engine is okay besides the noise. Thanks for the video, it helps.

Please go over this guide and get back to us. Also, let me know what you find when you remove the valve cover.
