1981-1982 FIREBIRD MODELS WITH CERTAIN RPO LG4 5.0 LITER ENGINES
General Motors has determined that some 1981-82 Pontiac Firebird models may develop restricted catalytic converters resulting in poor engine performance or a no start condition.
To prevent the possibility of the condition occurring, it will be necessary to revise the catalytic converter on the involved vehicles.
Involved are certain 1981-82 Pontiac Firebird models equipped with engine and emission systems described within the following vehicle breakpoints:
Engine Assembly Beginning Up To And Model VIN Code Plant VIN Including ----- -------- -------- ---------- ---------- Certain 1981 Firebird H Norwood (N) and SOP EOP Formulas & Trans Ams Van Nuys (L) with RPO LG4 5.0 Liter Engine and 4-Speed Manual Transmission

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.
Whenever a vehicle subject to this campaign is taken into your new or used vehicle inventory, or it is in your dealership for service in the future, you should take the steps necessary to be sure the campaign correction has been made before reselling or releasing the vehicle.
Owners of vehicles involved in this campaign, as records available to Pontiac Motor Division indicate, will be notified by Pontiac Motor Division (see copy of owner letter included with this bulletin).
Owners who have previously had their catalytic converters replaced with the single bed bead converter Part Number 25056364 outlined in Pontiac Dealer Technical Bulletin 82-T-89 for 1982 vehicles with automatic transmissions OR with the dual bed bead converters Part Numbers 25056675 or 25056676 outlined in Pontiac Dealer Technical Bulletin 82-T-97 should not receive notification or appear on the dealer's vehicle listing.
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 the owners involved in this campaign.
These computer 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 the law in several states. Accordingly, you are urged to limit the use of this listing for the follow-up necessary to complete this campaign.

The catalytic converter beads contain platinum, palladium and/or rhodium. Additionally, the beads may be finely coated with lead compounds. Therefore, precautions should be taken to minimize dust generation during the replacement procedure. These precautions include:
A. Catalyst dust should be controlled by wetting with water prior to bead removal as described in Step 6 of PART II - CONVERTER REMOVAL, PREPARATION AND INSTALLATION.
B. The use of a suitable dust mask, rubber gloves and safety glasses is recommended when handling catalyst beads.
C. Applicable OSHA standards should be reviewed.
D. Allow converter to cool before handling.
1. Raise vehicle on hoist.

Dear Pontiac Owner:
General Motors has determined that certain 1981 and 1982 Pontiac Firebird models may develop restricted catalytic converters resulting in poor engine performance or a no start condition.
To prevent the possibility of this condition occurring, it will be necessary to revise the catalytic converter on your vehicle.
Instructions for making this correction have been sent to your Pontiac Dealer.
Please contact your dealer to arrange a service date to have these modifications performed. The labor time required to perform these modifications is approximately one hour. Please allow additional time for the dealer to process your vehicle.
The enclosed owner reply card identified your vehicle. Presentation of this card to your dealer will assist in making the necessary correction to your vehicle in the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage paid owner reply card and returning it to us.
We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with your Firebird.
General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
