Stutter after ENDYN install
So I installed the Endyn kit on my car and now I have a partial throttle stutter/miss while driving the car for a minute or two. I did everything according to the instructions and it drove fine before the install. I am running Hondata tuned by Tony1 and it has always ran perfect. The only thing that i did when doing the install is totally remove the factory PCV system, vaccum cap the mani, and R&R the charge piping. I was just wondering if anyone has heard of or had any experience with this problem after installing the Endyn kit? Or has any suggestions, thanks

Re: Stutter after ENDYN install (FredoSP)
The PCV valve serves as a source of air at idle and low throttle angles, as oil vapor is passing through it into the manifold. If you plug the manifold where the PCV valve was originally routed, you either have to place a jet or adjustable air-control valve in it, or the idle will drop, since there's less airflow.
Most applications require that you reset the idle using the process outlined in the Helms manual if you're not using the PCV valve in the system.
You'll need to unplug the wiring from the IAC valve, and adjust the idle using the large brass screw located in the front of the throttle body. Once you have the idle RPM set where you want it, turn the engine off, reset the ECU by pulling the proper fuse, or disconnecting the negative terminal from the battery, reconnect the wiring harness to the IAC, and you're good to go.

I also talked ot the people at Endyn and they said to take the filter off of the top of the can and to just run the PCV valve. They said if it has already been tuned before the install then it might change A/F's. But I like your idea also, it makes sense. Have you had this problem before and solved it like this? I think I will try resetting the idle and if that doesn't work then I will just take the filter off and try it that way. Thanks for the input
