I’m fighting a high idle issue and I’ve sprayed carb cleaner all around the intake manifold, throttle body gasket, and all hoses under vacuum. I think the culprit is my PCV valve. I have a new one installed and it’s functioning properly. The stock hose has no leaks but at idle the right angle portion that connects to the throttle body collapses completely and partially pulls my pcv valve out of the cover. Would that cause an idle issue? Also is the PCV valve supposed to have a gasket between it and the valve cover? Thanks for any help you can give.
