What is the purpose and function of the EGR Vacuum Solenoid and EGR Valve on Pontiac Firebird?

The Exhaust Gas Recirculation (EGR) system reduces NOx emissions by reintroducing exhaust gas into the combustion chamber via the EGR valve on the intake manifold. This valve, opened by manifold vacuum, operates primarily during warm engine conditions above idle. The system adjusts gas flow based on manifold vacuum and exhaust backpressure, using a negative backpressure valve. An ECM-controlled solenoid refines EGR flow, receiving input from various sensors. Excessive EGR can cause stalling or surging, while insufficient flow might lead to engine overheating or emission issues. To maintain the system, inspect hoses and connections, ensure EGR valve operation, and check the solenoid. Replace faulty parts and clean the valve and passages when needed.
