inspection
So i went to inspection and failed eissions. this is the second time i failed. its a '92tbi 305 with 166,xxx and no mods but headman headers and y- pipe, it got 14xx for NOx, 16x for CO, and .80 for HC. at first my air pump was disconected so i reconected it. i have no codes and all of my conections are good. so i took it back and i stil failed. this time my HC went down but my NOx went up 500 and CO whent up 10-20. anyone have any idea ware to start
