Date: 910301
Campaign - Ignition Coil Cracked
Number:
90-E-01
Date:
March 1991
Section:
6E3
Subject:
QUAD 4 IGNITION COIL
Models/Years:
1987-90 CUTLASS CALAIS AND
1990 CUTLASS SUPREME WITH 2.3L ENGINE (VIN CODE D or A)
CONDITION
General Motors has determined that some 1987-90 Oldsmobile Cutlass Calais models and 1990 Cutlass Supreme models equipped with 2.3L (VIN Code
D or A) englnes (options LD2 or LGO) may develop cracks in the case of the I.D.I. (Integrated Direct Ignition) coil at the high voltage terminals. As the
cracks grow, external arcing occurs between terminals and/or terminal to coil frame resulting in intermittent misfire, rough idle, and ultimately a "no
start" condition when the coil falls completely.
Dealers are to inspect the ignition coils, and, if necessary, replace coils as instructed in the SERVICE PROCEDURE section of this bulletin.
VEHICLES INVOLVED
