'99 Contour SE Sport. Started this morning and CEL came on. Went to AutoZone and the reader said 'P0133, bank one of one, slow reaction time'. Only one code. This is regarding the oxygen sensor just past the pre-cat on the front manifold, correct? Is the Oxygen sensor bad or is there something else causing this? Just wonder if this code is masking another problem.
Thanx guys/gals!
BTW, it is the V6!
