I once had an ignition problem that I thought was due to a bad output
transister on an acura integra ECU.  I had tested the coil and replaced
the
ignitor.  I pulled ECU and removed its cover and sat in awe at
the quality of it's construction.  I decided to look elsewhere and the
problem
turned out to be the coil that ohmed out as perfect.  An O'Scope on the
signal
from ECU to Ignitor showed a good signal.
