joeyd50 Posted April 22, 2008 Share Posted April 22, 2008 I really should know this, I have a 1994 Nissan P/U 4X4 with 3.0 motor, what should the spark plug gap be? The guy at Auto Zone said .032 when I took the plugs out they were a lot bigger then .032, I called them back and they said .032 What should the gap be? Thanks Joe Link to comment Share on other sites More sharing options...
GhostPath Posted April 22, 2008 Share Posted April 22, 2008 Spark plug gap opens as the spark plugs are used and wear down through spark erosion. The gap should be .032, and your plugs were probably in there far too long. Link to comment Share on other sites More sharing options...
