Failed inspection error code PO442
ML320 1998 The error reads small leak in evap system and secondary air injection m/l is not ready. Gas cap is ok, replaced some vac. lines and the 3-way vac. connecter by the egr tube. Thats all the questionable lines I see. Cleared the error code and it came back on within 10 miles. Any suggestions, trying to fix this myself. Put on new egr and tube and fixed that error.
