General Motors has decided to conduct a Voluntary Emission Campaign involving certain 1996-97 C/K, S/T, M/L, G and P model vehicles equipped
with 4.3L (RPO L35 or LF6), 5.0L (RPO L30), and 5.7L (RPO L31) engines. Due to Service Parts Catalog part number reference errors, these vehicles
may have been serviced with an incorrect Linear Exhaust Gas Recirculation (LEGR) valve according to warranty records. An incorrect LEGR valve may
cause the On-Board Diagnostic emission system to not operate as intended and/or cause driveability complaints.
To correct this condition dealers are to install the correct LEGR valve on vehicles identified as having been serviced with incorrect part number.
