I have a 2001 Toyota Corolla 1.4 with 100,000 miles. I got this code, P0171 (I think) something or other was "lean." Anyway, I was advised to change the O2 sensor. So, when the light came on again after I had it changed I got the same code. SO, I had the other O2 sensor replaced. Honestly, I had no clue there were two of them when I had the first one replaced! Now the car runs terribly! What could be the problem? I would REALLY appreciate your advice! Thanks,
have the same problem?
