Hi Scotty,

I replaced a bad upstream O2 sensor on my 06 Suzuki Forenza. I can tell that the car is running much better but I am still throwing a P0133 code. Any thoughts?




Test the O2 sensor?

the software here was acting up and that was a test I was doing. So here's your real answer: Give it a few days of driving, and also do this cleaning video https://www.youtube.com/watch?v=5icTmYItwiE

Thanks Scotty. I was wondering what was going on this morning. I tried to post my question 3 times and it wouldn't let me. So if you got like 3 of the same post I am sorry. Thank you for the information and all of your help.

no problems
