INSPECTION

The Saturn TBI assembly gasket kit contains two fuel meter to throttle body gaskets stamped with the last five digits of the part number. When replacing this gasket, you must first identify the fuel meter body part number, and then select the correct gasket for that application.

NOTICE: Failure to use the correct gasket may cause a vacuum leak and will result in a rough or unstable idle speed and possible driveability problems.

1. Identify the last five digits of fuel meter body as shown in diagram.

2. Select the gasket according to the following criteria:

^ If the last five digits of fuel meter part number are 84664, use gasket part number 86192.

^ If the last five digits of fuel meter part number are 09577, use gasket part number 09578 (this gasket is marked with white stripes on two outside edges to aid identification).
