CALIBRATIONS: 3-03A-R01-R12-R13
WARNING:
This modification is authorized only for the listed engines. Performing this modification on other engine calibrations is unauthorized and
could create liability under applicable federal or local laws.
Poor cold start, engine surge/hesitation, or backfire on tip-in during the initial 2 to 3 minutes of engine operation after an overnight soak in ambients over
55~F, may be caused by an excessively lean fuel/air ratio. This concern can be serviced by installing a 1984 processor. Since a 1984 processor wiring
connector is different than the 1983 connector, a revised wiring harness (12A581) adaptor is required in addition to other associated EEC system
components.
All parts required for this concern are included in a kit and are priced at $209 net (no stock order discount or PIPP allowance) per kit dealer cost, with a
$100 credit when all substituted parts are returned through the Warranty and Parts Return Center. The pricing is consistent with current processor
pricing. Service kits will be available for a limited time period beginning immediately and ending September 30, 1985.
Authorized Modifications Decal
Obtain an Authorized Modifications decal and list the date, dealer number and summary of alterations performed. Select a prominent place adjacent to
the Vehicle Emission Control Information decal suitable for installing the Authorized Modifications decal. Clean the area, install the decal and cover it
with a clear plastic decal shield.
