NOTICE: This bulletin is intended to advise you of Special Coverage that is being extended to all owners of front-wheel drive Buicks produced with 3.0L and 3.8L engines in 1986 and 1987 model years. This bulletin supplements Bulletin 87-6E-29 (Corporation No. 006501) until December 31, 1992.

Some 1986 and 1987 Skylark/Somerset, Century, LeSabre, Electra/Park Avenue, and Riviera model vehicles with Engine VIN Code 3, B, and L may be experiencing intermittent stalling. To correct the stalling complaints, a comprehensive diagnostic procedure manual was developed and released in July, 1990 (Service Bulletin 87-6E-29).

To assist owners on these vehicles that are still experiencing intermittent stalling, Buick is providing Special Coverage for this condition until December 31, 1992 or 100,000 miles whichever comes first.

Please note that this is not a recall campaign and therefore not intended to be used on all vehicles. It should only be applied if an owner has an intermittent stalling complaint. It is not intended to replace regular maintenance that should be done on a routine basis.

We ask that dealers carefully adhere to the intent of this Special Coverage program. This coverage is being established in the interest of customer satisfaction. It is expected that all dealers will fully support this program. Vehicles which fall within the special coverage program that are currently experiencing stalling should be promptly corrected.
