Hi, I have a 2013 Civic Si that is Supercharged by Kraftwerks. I have a strange idle problem that occurs at random while shifting into neutral (perhaps to coast before a redlight or similar scenario). The idle will on occasion fall correctly and hold steady at or around 900RPM, on other instances it will either fall and recover to 1500RPM and hold steady until completely stopped, at which point it will fall to 900RPM, on other instances it will fall to 900RPM and slowly climb to 1700RPM and drop and climb again creating a surge in idle if you will. Any ideas are much appreciated. I have seen a video on youtube with a similar if not exact same problem. https://www.youtube.com/watch?v=SutRsEQUL8g
"Idle problem after RBC swap, 9th Gen"

Thanks Everyone... Really...

Do you mean a issue like this?:

While He does have an idle issue it does not appear to be the same. The video I found on youtube matches the issues almost exactly... Where the referenced FN2 falls then recovers mine does not fall to 600 ever.
