The 2.5 had lots of changes for model year '87.  Through '86, they had a
distributor and used a C3 ECM.  For '87, they went with DIS and a P4
ECM.  Lots of other parts (TBI unit, A/C compressor, etc.) also changed
for '87.  It may look like a mid year change because most of the 2.5
equipped cars used the same body style in both '86 and '87.
