#### MODELS: CERTAIN 1998 PONTIAC BONNEVILLE; OLDSMOBILE REGENCY, LSS, EIGHTY EIGHT; AND BUICK-PARK AVENUE, LESABRE (C,H CARS) EQUIPPED WITH 3.8L ENGINE (RPO L36, VIN K)

General Motors has decided to conduct a Voluntary Emission Campaign involving certain 1998 Pontiac Bonneville; Oldsmobile Regency, LSS, Eighty Eight; and Buick Park Avenue and LeSabre (C, H cars) model vehicles equipped with a 3.8L V6 engine (RPO L36, VIN K).

To correct this condition, dealers are to reflash the vehicle PCM with new calibration software. Dealers are also reminded to follow the service manual diagnostics procedure in response to any SES light illuminated.

VEHICLES INVOLVED

Involved are certain 1998 Pontiac Bonneville; Oldsmobile Regency, LSS, Eighty Eight; and Buick Park Avenue, LeSabre (C-Car, H-Car) model vehicles equipped with a 3.8L engine (RPO L36, VIN K) and built within the following VIN breakpoints:

Computer listings containing the complete Vehicle Identification Number, customer name and address data have been prepared,and are being furnished to involved dealers with the campaign bulletin. The customer name and address data furnished will enable dealers to follow-up with customers involved in this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

These dealer listings may contain customer 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.

A new flash program has been released to address the conditions mentioned above. The cumulative calibrations for all carlines and years affected by this campaign will be included and available from the Service Technology Group beginning with the # 1 Techline CD ROM release of January 6, 1998. The following tracking table shows the individual carline calibration update number. Do not attempt to order the calibration number from GMSPO.

CUSTOMER NOTIFICATION

Customers will be notified of this campaign on their vehicles by General Motors (see copy of typical divisional customer letter included with this bulletin - actual divisional letter may vary slightly).

In order to ensure full protection under the emission warranty, and the right to participate in future recalls, the customer notification letter recommends that customers have their vehicles serviced as soon as possible. It also advises that failure to do so could legally be determined to be lack of proper maintenance. The vehicle may fail a state or local emission inspection test if the recall work is not completed.

DEALER CAMPAIGN RESPONSIBILITY

All unsold new vehicles in dealers' possession and subject to this campaign must be held and inspected/repaired per the service procedure of this campaign bulletin before customers take possession of these vehicles.

Dealers are to service all vehicles subject to this campaign at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward.

Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. This could be done by mailing to such customers a copy of the appropriate divisional customer letter accompanying this bulletin. Campaign follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.

In summary, whenever a vehicle subject to this campaign enters your vehicle inventory, or is in your dealership for service in the future, please take the steps necessary to be sure the campaign correction has been made before selling or releasing the vehicle.

When a California emissions campaign is completed by a GM dealer, the dealer must provide the vehicle owner a "Proof Of Correction Certificate" which the owner may need to present to the California Department Of Motor Vehicles (DMV) when renewing their vehicle registration. Without this correction certificate, the owner may be unable to renew their vehicle registration.

Additional Certificates can be obtained, at no charge, from VISPAC, Incorporated by calling 1-800-269-5100, Monday through Friday, 8:00 A.M. to 4:30 P.M. Eastern Standard Time. Ask for GM Item Number 1825 when ordering.

SERVICE PROCEDURE

#### IMPORTANT: Correct any SES light indication or driveability complaint using appropriate service manual procedure prior to beginning reprogramming. As needed, submit normal warranty claims using published Labor Time Guide operations for repair reimbursement.

#### IMPORTANT: A Techline CD ROM, titled "Disc #1" (Jan 06, 1998), or later software, will be required to properly program all vehicles. A Tech 2 will be required to reprogram all vehicles involved. Also, refer to the Techline Customer Support Center help line.

1. Prep Vehicle for Powertrain Control Module reprogramming.

2. Flash PCM EE PROM using the matching vehicle software on the 1998 #1 CD ROM or later. Refer to up-to-date Techline equipment users instructions.

3. Install GM Campaign Identification Label.

4. California dealers only, provide owner with a "Vehicle Emission Recall Proof Of Correction" certificate.

CAMPAIGN IDENTIFICATION LABEL

Each vehicle corrected in accordance with the instructions outlined in this Product Campaign Bulletin will require a "Campaign Identification Label". Each label provides a space to include the campaign number and the five (5) digit dealer code of the dealer performing the campaign service. This information may be inserted with a typewriter or a ball point pen.

Each "Campaign Identification Label" is to be located on the radiator core support in an area which will be visible when the vehicle is brought in by the customer for periodic servicing. When installing the Campaign Identification Label, be sure to install the clear protective covering. Additional Campaign Identification Labels can be obtained from VISPAC Incorporated by calling 1-800-269-5100 (Monday-Friday,8:00 a.m. to 4:30 p.m. EST). Ask for Item Number S-1015 when ordering.

Dear GM Customer:

This notice is sent to inform you that General Motors is conducting a customer satisfaction recall campaign, involving an emission component, that includes your vehicle.

REASON FOR RECALL: General Motors has determined that certain 1998 Pontiac Bonneville; Oldsmobile Eighty Eight, LSS and Regency; and Buick Park Avenue and LeSabre model vehicles equipped with 3800 Series 11 (normally aspirated engine) may not control engine spark timing properly during steady-state driving conditions. This could lead to engine spark knock and potentially permanent engine damage.

WHAT WILL BE DONE: To prevent the possibility of this condition occurring, the calibration inside the Powertrain Control Module on your vehicle will be updated with an improved design. This service will be performed for you at no charge,

CONTACTING YOUR DEALER: Please contact your dealer as soon as possible to arrange a service date. Instructions for making this correction have been sent to your dealer. Please ask your dealer if you wish to know how much time will be needed to schedule, process and repair your vehicle.

If you experience any trouble scheduling your vehicle or you have any questions regarding this recall action, please contact the Customer Assistance Center at the number below:

EMISSION LAW INFORMATION: In order to ensure your full protection under the emission warranty made applicable to your vehicle by Federal Law, and your right to participate in future recalls, it is recommended that you have your vehicle serviced as soon as possible. Failure to do so could legally be determined to be lack of proper maintenance of your vehicle. Also, your vehicle may fail a state or local emission inspection if the recall is not accomplished.

IMPORTANT MESSAGE FOR CALIFORNIA RESIDENTS

The California Air Resource Board (CARB) requires vehicle emission recall campaigns be completed prior to California registration renewal. Uncorrected emission recall campaigns will result in the inability to renew your California vehicle registration.

At the time of emission campaign completion, your California dealer will issue a "Proof of Correction Certificate". Keep this certificate and, if required, present it to the Department of Motor Vehicles when renewing your California registration as proof of campaign completion.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our product.
