      1228321 is the correct ECM for '89 Cavalier 2.0 All replacement " Modules
   are remanufactured  Delco for Field Use. New ECM - PCM is assembly line only
   and most of this scheme is connected with EPA regs, not Manufacturers.
  Unless the case or connector pins show obvious  corrosion there shouldn't 
be a problem,
although a continued bath of engine coolant could migrate into the harness 
and cause
problems. As an aside "flood victims usually respond to disassemble , hot 
soap and
water wash , dry and your OK. Check the ECM connectors carefully and adjacent
wiring for moisture intrusion.  Reman ECM's must pass performance standards of
a new ECM - PCM . Usually modules with a history of field service 
complaints are
replaced with a Revision Part number that has the same features of the original
assembly line part , less the bug that caused the field problems. Revisions 
in this
regard are improved reliability in service.
