  • One hose connector and two bolt holes

Detailed Description

Standard Ignition EGV123 is an exhaust gas recirculation valve for emission system repair on the 1987 Plymouth Expo, 1983 Dodge Colt, and 1980 Plymouth TC3. The mechanical design supports direct replacement service, while the stainless steel construction and reinforced silicone diaphragm are built to handle heat exposure common in EGR operation. This part cross-references EGR308 and EGR945 for the same application.

Common Issues This Part May Address

  • EGR valve sticking or failing to open and close properly
  • Rough idle related to exhaust gas recirculation faults
  • Emission test failures tied to EGR system malfunction
  • Driveability concerns caused by restricted exhaust gas recirculation flow
  • Vacuum or sealing issues at the EGR mounting point

Installation Notes and Tips

Verify the OE number, connector layout, and bolt-hole pattern before installation. The included gasket should be used during replacement to help ensure a proper seal. Confirm hose routing and mounting surface condition, and inspect related vacuum or emission components for wear before returning the vehicle to service.

Quality Assurance

Standard Ignition maintains quality control throughout the manufacturing process, from component selection through finished product inspection. That process supports consistent fit and function for emission control service.
