If your Jaguar Super V8 failed the emissions test due to high NOX, the EGR Valve is most likely the issue. If your Jaguar is running rough or has poor fuel mileage, replace the Super V8 EGR Valve and gasket.
The Jaguar Super V8 Oxygen sensor is a critical part of the emmision control system and should be replaced as soon as it fails. Make sure to check the Jaguar Super V8 diagnosics codes for proper replacement of the O2 Sensor.
