I have low compression in # 2 and 3 cylinders (125 psi) and compression on
# 1 and 4 cylinders is (170 psi).  The #2 and #3 are not firing and the
plugs are wet.  Both went at the same time and not sure what was the
problem.  Had a bit of valve tap before it happened.  I have changed the
plug wires, and checked for spark.  There is spark at all cylinders but 2
and 3 seem low (is there a way to test).  Everything moves freely.  Is
there another compression test to run.  Thanks for the help
