Keeping y'all posted on my 95 Ford aerostar.. Engine runs good , but
still has a little miss and of course bad vibration...  
I have done a lot of work on it over the past few days. and heres whatI
have found.. I bought in inline spark tester that connects between the
wire and sparkplug and I got really good spark from what I Saw of the
tester .. best tool I own right now I Think.. also bought a noid light
set for checking the injector harness wiring agan everything checks
fine..I also pulled the upper intake plenum to get at the injectors so I
could listen to the clicks used my homemade tool to listen to each
injector and they all were working..

The only thing puzzling me is ... when the engine was running I pulled
the wiring from the injectors that were accessble and whitch is the
right side. I pulled the Front and back first and each time was a
noticable difference in how the engine runs yet when I pulled the one in
the midde it was not at all noticable whitch I find strange.... maybe
not a big deal I don't know yet this injector works so who knows ??
maybe it doesn't work as well as it should...
