Technical Service Bulletin # 90C11
Date: 910302
Campaign - Faulty Ignition Coil
Number:
90-C-11 Date: 03/91
Subject:
EMISSION CAMPAIGN - 90-C-11 QUAD 4 IGNITION COIL
MODELS AFFECTED:
1988-90 GRAND AM AND 1990 GRAND PRIX WITH 2.3L ENGINE (VIN CODE D OR A)
TO:
ALL PONTIAC DEALERS
General Motors has determined that some 1988-90 Grand Am models and 1990 Grand Prix models equipped with 2.3L (VIN Code D or A) engines
(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 teminal 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.

Involved are certain 1988-90 Grand Am models and 1990 Grand Prix models equipped with 2.3L (VIN Code D or A) engines (options LD2 or LGO)

NOTICE:
Vehicles listed in Pontiac's records as previously repaired under Labor Operation T4676 were deleted from this campaign.
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 (VISS) for verification.
Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the complete Vehicle
Identification Number, owner name and address data, and are furnished to the involved dealers with the campaign bulletin. Owner name and address data
furnished will enable dealers to follow-up with owners involved in this campaign.
These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle
registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow-up
necessary to complete this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.
Owner Notification
Owners will be notified of this campaign on their vehicles by Pontiac Division (see copy of Owner Letter included with this bulletin).
DEALER CAMPAIGN RESPONSIBILITY
If there is evidence of intentional disablement of the emission system, the dealer is to notify the vehicle owner of this condition and ask if he/she wants
the system restored. Restoration cost is the responsibility of the owner.
Dealers are to service all vehicles subject to this campaign at no charge to owners, regardless of mileage, age of vehicle, or ownership from this time
forward.
