Default 97 maxima code P0400

I have been trying for 2 months to get my car to pass NYS inspection! I keep getting P0400...which I know what the code is and what it means. I have a scan tool and have cleared the code and I'm waiting for the modules to clear. I have 5 mods to clear every time I throw a check light. A couple days ago I got the green light but 3 days later I threw the same code. I was wondering if anyone knew how long I have to drive and go through the cycles before all the modules clear. Not sure if I'm just driving it too long or not enough.
