I have to smog my 96 sometime this month as the tags are due. I have had the engine light come on and off for the past 600 miles for code 1443 (purge flow sensor). I replaced the sensor last night (I hope that cured the problem). I disconected the battery, then I replaced the sensor. When I started the car, the engine light was off. Do I need to do anything else before I go to smog the car? Is there a history I have to clear or did I do that when I disconnected the battery?
