81 Secondary -Air Injection Diverter (AIRD) solenoid circuit failure. 82 Secondary Air Injection Bypass (AIRS) solenoid circuit failure. 84 EGR Vacuum Regulator (EVR) circuit failure. 85 Canister Purge (CANP) circuit failure. pretty much if you ripped your EGR out, that pretty much takes care of them. oh , and u might want to bookmark this link [http://www.freeautomechanic.com/diagnostictroblecodes7.html](http://www.freeautomechanic.com/diagnostictroblecodes7.html) ---
