no. you're overthinking it. Your combustion chamber doesn't get "gunked up". It's just got a little carbon in it. Nothing more.

Dude just change the oil, put in new plugs and drive your car...not sure what you're so worried about.

Well that's got nothing to do with plugs and cam shafts then. You just have a vacuum leak probably. Change your intake boots and look for other broken vacuum hoses.

Plugs generally not going to fix lean codes (nor will cleaning the cylinders) - that is a separate issue.

The rough idle is likely caused by the lean codes and from what I have read - you have not finished the work that would effect the lean codes.

Indeed, I am very overwhelmed of the complexity of that process to replace ccv and all the vacuum lines, cheap parts available, but scared to be honest
