Certain vehicles equipped with 4.8 litre or 5.3 litre engines do not comply with the requirements of CMVSS 1103 - Exhaust Emissions. Engines may have been built with the wrong Linear Exhaust Gas Recirculation (LEGR) valve which could limit the required air flow rate. A failed valve could cause the vehicle to fail to meet applicable emissions standards. Correction: Vehicles will be inspected and LEGR valve will be replaced with a new valve where required.
