Section:

SUBJECT:
QUAD 4 IGNITION COIL SUPPLEMENTAL BULLETIN
MODELS/YEARS:
1988-90 CUTLASS CALAIS AND
1990 CUTLASS SUPREME WITH
2.3L ENGINE (VIN CODE D or A)
THE INVOLVED VEHICLES SECTION OF EMISSION CAMPAIGN BULLETIN 90-E-01 IS REVISED FOR CLARITY.
CUTLASS CALAIS WITH ENGINE VIN CODE "D" AND CALIFORNIA EMISSIONS HAVE BEEN ADDED TO THE CAMPAIGN.
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) engines (options LD2 or LG0) 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 fails 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
Involved are certain 1987-90 Oldsmobile Cutlass Calais models and 1990 Cutlass Supreme models equipped with 2.3L (VIN Code D or A) engines

All vehicles listed on the dealer printout will require inspection, and as necessary, correction. Other suspect vehicles should be checked for campaign
involvement by utilizing the Vehicle Information Service System (V.I.S.S.) for verification.
