Subject: ENGINE MISS ABOVE 3000 RPM IN PARK OR NEUTRAL (INFORMATION)

Models
Affected: 1991 GRAND PRIX MODELS WITH 3.4L ENGINE


On 1991 Grand Prix models equipped with the 3.4L twin dual CAM V6, the engine calibration will not allow the engine to be "free-reved" above 3000 RPM.

If a customer comments that the engine will not rev above 3000 RPM in park or neutral, this condition is normal.
