# HESITATION ON ACCELERATION SERVICE PKG INFORMATION

#### VEHICLES AFFECTED: 1984 'T' Series Equipped With 1.6L Engine (Code C), Automatic Transmission and Non Closed Loop Emission System

Some early production 1984 'T' Series vehicles with automatic transmissions and non closed loop emission systems may have been built with incorrect accelerator pump discharge nozzles.

These vehicles may exhibit a light to heavy hesitation on acceleration at ambients greater than 20 deg. C or less than -15 deg.C. This condition is most noticeable prior to the choke being fully open.

Vehicles having the following production sequence numbers (last 6 digits of V.I.N.) or later will have the correct nozzle.

Chevette - 145096 Acadian - 701927 T1000 - 208407

If a vehicle exhibits these conditions a service package (P/N NPN 3017) may be ordered. This package contains a discharge nozzle, 2 discharge nozzle gaskets, an air horn gasket and 2 choke rod retainer clips. Refer to the appropriate Service Manual for installation procedures.

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.
