i recently gutted my friends cats on her 2000 t/a an installed o2 sims. no engine light for a week an half. i got the codes. the first time i only got p1153 and cleared it. second time the light came on i got p1153 and p1133. i know these codes both have to do with the front o2 sensors but i'm not sure how to get ride of the problem. cars runs fine blows a little smoke when cold. i think it might be running a little lean. any help would be great

Replace the front O2's.
