How did they determine an injector was bad???  I doubt it.  What is the HC
level?  Was the engine proerly warmed up?  Idling engine to warm up will
often load up CAT to cause failure.  O2 sensor is probably the problem.
 Injectors can be changed singularly.  Do not mix digijet with dijifant
control system.  Dijifant has improved idle control,(throttle bypas vs
ignition timing),  ignition timing and coil control provided by brain, not
separate module.  # wire O2 sensor,(heated for faster response).  Digifant
more susceptible to erratic behavior from bad sensors/grounds
