# BUZZ FELT IN ACC. PEDAL NEW SPACER PLATE P/N

#### MODELS AFFECTED: 1994-1996 CIMARRONS

A throttle buzz condition may be exhibited by 1984 through 1986 Cimarrons equipped with THM 125C transaxles, Model CJC. The condition is most noticeable at idle in drive and less notiiceable as the vehicle begins to move. The affected transaxles were built prior to October 29, 1985 (Julian date 302) in Windsor, or prior to December 9, 1985 (Julian date 343) in Ypsilanti.

Beginning on these dates, 4 new design valve body to case cover spacer plate entered production designed to eliminate the buzz by reducing the diameter of the 1-2 accumulator valve bleed orifice. Reducing the diameter of the bleed orifice prevents rapid oscillation of the valve, which when transmitted to the throttle pressure valve causes it to buzz.

To correct a throttle valve buzz condition for models built before these dates, replace the original valve body to case cover spacer plate with the new spacer plate (P/N 8660569).

Refer to Section 7A of the appropriate Service Information Manual for removal and installation procedures. Refer to Figure 1 for transaxle identification information.

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.
