RE: Fouled plug, injector problem - exhaust manifold crack?

[Robert Abatecola <robert@xxxxxxxxx>]

Jeff and everyone else,

Thanks for the pointers.  I swapped plugs between #3 and #4.  The 
problem stayed with #4.  I also checked for spark using a grounded 
spare plug.  Spark checked out okay.  I installed a new plug on #4 
(Bosch Platinum is all I could find locally).  Again, the problem did 
not change.

Is it possible (and easy) to test the injector connection?  What 
should I do next?  Order a new injector?  :-)
