rough idle

Car sounds like it has a cam at idle, no check engine light or codes

Probably a slight/intermittent misfire. I'm currently battling the same issue.

If it helps at all I had 6 burned up plugs, and 1 wire that wasn't on all the way lol. Guess the previous owner didn't like the looks of the passenger side plugs... Runs like a dream now
