I've failed my smog test 3 times in a row within a week. They told me it was the EGR. So I changed my EGR Valve, EGR Solenoid, and my EGR Pressure sensor. The vacuum lines running from the EGR Valve to the Solenoid are clean, no blockage.
I ran a OBD1 test, and the code 326 keeps popping up.
I checked the Catalytic Converter temps, before and after the Cat. Before it's about 300F and after, around 290F. I know it has to be hotter after to insure the pollutants are being cleaned before leaving the exhaust.
