While a few of you are having a problem with not enough spark, I am having
the opposite problem.  I put the battery in tonight and started to run
through systems checks.  The test modes in the EC2 are really nice features.
Injectors and new injector disable switches seem to be working fine.  The
problem is with the coils...  Way too much spark if that is possible.

I planned to test the LS1 coils 1 at a time but quickly found that 2 of the
coils are arcing past the rubber boots of the spark plug wire, one more than
the other.  I thought maybe the rubber had gotten old (though not that
old) so I swapped in one of the wires that was not leaking - but that did
not solve the problem.  I took all the wires off entirely, and sparks were
flying out of the socket and arcing across several inches to reach the
control harness for the coil.  The other coils were not doing that, though
they were making normal sparks when connected to a spark plug.

I assume this is not normal.  Does anyone know of a condition that would
make the coil voltage go through the roof like that?  The coils did get a
good dousing of coolant 1.5 years ago.  Also, I notice that the coils are
drawing 3 amps even when not running.  Time for some new coils?
