The above models may experience a rough idle condition (at idle or off-idle) that is generated by a lean mixture. Normal service manual diagnostic procedure should be followed to isolate the cause of the lean mixture.

The EFE isolator/gasket below the carburetor should be checked for vacuum leakage, contributing to the lean condition. If the EFE isolator/gasket is identified as the vacuum leak source, then the isolator/gasket should be replaced per service manual procedure.

The EFE isolator/gasket (Part Number 14018761) is available from GMSPO on their "Target Program" and is covered by GM's 5 year/50,000 mile emission warranty.
