2004 Smog Test. OBD Report continues stating that "Catalyst, Evaporative System, Oxygen Sensor Heater, & Oxygen Sensor has not completed this test".
Put factory exhaust manifold back on with all (4) factory cats to pass the Wisconsin emissions test. I understand when the battery is disconnected the ECU resets and prior smog data gets erased. Have driven over 150 miles since reset. Any suggestions?
