wasnt really sure where to post this so i guess ill try here

ok guys me and justin has been messin with my car for a while and it just threw another code (code 1153). when i googled this i found a link to the vette forums where people are havin same problems as me, runnin extremly rich, like 10-11mpg rich. even though the code had somethin to do with the o2 sensor, we just replaced the o2 a week ago with a brand new one. when i was reading the thread on the vette forumthey started talkin about a 15 amp fuse was the cause of it. checked all my fuses and they are all good. i do have a bout 4 fuses missing which im gonna end up getting. any ideas anyone? thanks
