Hi List,
I've had intermittent ignition problems that seem to get worse when the
engine is completely warmed up.    The van hesitates and the RPM needle
bounces back and forth.  Sometimes it gets so bad that I can't even start
the van.  I've explored the AFM solution, i don't think that's it because
it's still a problem immediately after restart.  On one occasion i noticed
that the coil wasn't sparking at all but I thought the problem was with the
hall sensor.
I've epoxied the hall sensor in place and made sure I've got no shorts
there, cleaned all my grounds, checked my plugs etc but the problem
continues.
So now i'm wondering if I've got a bad coil.  Can these be tested?  Can they
be rebuilt?
Assuming the coil is ok and the hall sensor is ok, can a bad computer tell
the coil to stop sparking?
