How do you know the PCV valve may need replacing or cleaning? Does the engine idle or run a particular way? My engine idles rough and oscillates badly when either in drive or a/c on in drive; when in neutral, it idles smoothly. I would like to know before the check engine light comes on.
Thanks for any extra thoughts on this, Pat |
