CALIBRATIONS: All with T.F.I. Except EEC IV
Some May, 1983 built cars may exhibit engine miss, erratic operation (EFI not included) due to certain Thick Film Ignition (T.F.I.) modules. These
modules can be identified as follows:
1.
Check vehicle build date. The date stamp is either at the left or right side of the radiator support near the hood bumper or on the top surface of the
left hand shock tower. If the build date is from May 2, 1983 through May 26, 1983, proceed to step 2. IF the date is outside this period, proceed
with normal service diagnostic procedures.

2.
With the distributor and module on the engine, suspect modules can be identified by a slot (A) and a stamped lot code (B) located on the back
(diaphragm side) of the module connector (Figure 11).
3.
If the module contains a lot code (B) from 0163 through 0184 it should be replaced using the shop manual procedures in Section 23-05 and the
following notes:
NOTE 1: Scribe a mark on the distributor base and cylinder head before removal for accuracy of alignment upon reinstallation.

NOTE 2: Apply silicone grease, part number D7AZ- 19A331-A to module as shown in Figure 11.
