You will need to unplug the evap purge control solenoid because the outputs are inverted between OBD1 and OBD2 ECUs.

Just unplug the electrical connection. It will not hurt a single thing.

 

As described via email, try unplugging the evap purge solenoid. If you are still having issues after contact us.
