Harsh idle just began NO CEL
So had my valve adjustment done the other day at Blacktrax, was good stuff car drove fantastic afterward. Over the last few days however the car has bogged a few times, even stalled, and now the engine is really rough at idle, like the car vibrates and hums ALOT. There is no CEL or anything like that mostly just my own observations. I did notice at one point while I was letting it warm up that I could swear I heard clicking coming from the engine bay. I rarely ever never practically ever VTEC or 9k this thing. I drive it like an old man. Oil was changed 2k ago. Most posts suggest misfire etc or vaccum leak but I have no CEL so i'm a bit confused. Gonna check the PCV valve tonight for lack of rattle.

describe what you mean by really rough. If it's only been a few days since valve adjustment, i'd probably look at what's been worked on recently to double check. If it sounds like it's not running right, (I'm not there to judge, so I sincerely don't know) I wouldn't drive it until the issue is sorted.

Okay so its been what like 2-3 weeks since adjustemnt? Car was smooth, quiet etc before. Now at idle or especially when A/C / idle the car feels like im riding inside a freaking massager.

It might not even be your valve adjustment. It's very common for S2K's to damage at least 1 motor mount. I just had a valve adjustment done this past Monday. my car runs fine its quiet, but it idles pretty rough because of just 1 motor mount that needs to be replaced. It could be that.
