PCV/CCV idle issues
I recently removed my stock pcv/ccv system on my 1997 C5 LS1 and installed a oil cap breather, and a catch can assembly routing from the passenger valve cover to the intake manifold. I deleted the CCV from the passenger valve cover to the throttle body. Upon starting the car back up today, the idle is really rough and the car seems to be running rich. (Nothing else at all was changed in the car).. Any idea what might be causing this or what I can do to fix it? I guess I can reinstall some of the old components but is this something a simplt tune would fix? I have the HPtuners Pro so I can go that route if needed.
Thanks guys!
Thanks guys!

Well glad to hear this has happened to someone else before. How did you go about changing your airflow? Is there any quick fix in the tune? Any recommendations would be greatly appreciated.
