2005 pathfinder making a valve tapping when idling
I noticed the other day when the RPM is just right when idling I hear a valve tapping. When the idling is just a little quicker or slower it is ok. Could it be I got a bad batch of gas? The problem is not consistent. I only have 15K miles on it. I am taking to Nissan along with the 4WD problem.
