Seems like the problem wont go away upon cold start this happens it starts yet idles low i gotta push the gas to at least 2k for about 35 seconds
(sorry for text message ringtone)

and it begins dropping low to about 300 and my car begins to rattle ALOT.


but once the engine is all warmed up it idles here and everything goes back to normal.(same vid posted from previous post)


this coldstart is becoming an issue now any ideas guys?

I've been putting some thought into this and I can't come up with anything at all. On cold start, your ECU ignores all sensor input and runs on a base map. If anything, your problem should be the other way around where problems start to develop after the engine has warmed up. The only thing I can think of is that it might still be ISCV related. My ISCV is only about half working at the moment and I don't have a code for it, so it has to be pretty bad before the ECU starts to care. Rdyzz did the research and found that the Civic valve will work, and his hasn't had any issues at all so I doubt if it's the Civic valve unless yours was faulty right off the shelf. It would still give you issues after the motor has warmed up though. I suggest unplugging sensors one at a time when the motor is cold to see if any of them make a difference.
