Dan,
 
An injector is certainly a possibility, = or a bad=20 EGT probe.  A simply way to test the probe is to trade=20 places with another probe, like #2.  If there's enough service = loop in=20 the EGT leads you should be able to swap them around with changing the=20 wiring.  In that case (i.e. the probe electrical connections = weren't=20 changed) if the #4 probe, which is now on the #2 = cylinder, still=20 reads low it's a probe problem.  If the #2 probe now reads low it's = an=20 injector/cylinder problem.  I had a low EGT on a Commander 112 = that=20 turned out to be a bad cam lobe.  Hope that's not your=20 problem.
