So I’ve been hunting down a slight miss on idle for a little while.
if I remove the hose going from the pcv to the intake manifold and block it off the idle is instantly as it should be.
The hoses had quite a bit of oil in too.
i replaced the pcv and both hoses today and it’s idling worse.
both pcv’s are fine under boost pressure.
could it be that the new pcv is doa or could there be another issue that the new one is showing up?
bit stuck on what to do next.
