Corp. Ref. No. 706501R
SUBJECT: ENGINE DOES NOT STAY RUNNING ON INITIAL COLD START, INTERMITTENTLY WILL NOT STAY RUNNING ON DECEL, OR EXHIBITS A FALSE CODE 32 OR E032
MODELS AFFECTED: SOME 1987 CENTURYS, LESABRES, ELECTRAS AND RIVIERAS EQUIPPED WITH 3.8L SFI ENGINES (VIN CODE 3)
Some 1987 models equipped with a 3.8L SFI engine (VIN Code 3) may experience one or more of the following conditions:
^ Engine will not stay running on the initial start when the engine is cold
(with proper fuel pressure and no leak down).
^ Engine intermittently won't stay running on decel under closed throttle conditions (with proper scanner readings and minimum air rate).
^ An intermittent "Service Engine Soon" light with a stored false code 32 on
Centurys, LeSabres, and Electras/Park Avenues, or a false code E032 on Rivieras.
If any of these conditions are experienced on a vehicle when the basic engine, controls and systems are performing properly, and cannot be repaired by using currently published service and diagnostic procedures, it may be necessary to install a new service PROM.
These PROM's are currently available through General Motors Parts Operation under the following part numbers:
