P0441 code 00 tiburon help please
 

Just a week ago I got a 00 tiburon for my girlfriend and it turned out they had removed the check engine bulb. I failed emissions and fix the bulb and had a smoke leak test done. The mechanic said the purge valve was bad so I personally replaced it. Had the code reset and the next day passed emissions. Well the day after that the light came back on and it's kicking P0442 which is same description as the P0441. Any suggestions to fix the problem all together?
