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.

Any solutions?

Regards, Frank

OBD1 326 indicates that the EGR pressure sensor is reading pressure values that are out of the range deemed to be normal.

Along with the results of your pre/post-cat temperature test, this is strong evidence that the catalytic converter is clogged.

The solution would be to replace the catalytic converter.
