A question for you CIS(or and FI) gurus out there. Replaced the injector and it did not help

[johncworden at verizon.net (John C. Worden)]

Ok, I replaced the #4 injector and there is no difference.  Afterwards I 
also rechecked the DPR,
replaced the dist. cap and rotor and rechecked/adjusted the timing.  The 
thing still isn't right.
To answer some of the responses:
Michael- I didn't know it was a fuel problem, but ignition/spark is right 
on, so that was my next
area to look at(I should have included part of my email from a day or two 
ago that told of the
problem and what I had checked)
Tberk-I have looked for vacuum leaks and have not found any.  Doesn't mean 
I haven't missed one,
but I have looked thoroughly.
And for everyone that mentioned the airflow plate, it's bearings and the 
dist.  I can pretty much rule
that out because the plate responds very smoothly, and fuel increases as 
the plate is lifted.
Well I will take another look at the ignition section of Bentley tomorrow, 
it's possible I've missed something.
