my car has been runnin rough and sputtering what could it be a cel code was bank one o2 sensor which side is that and could it make my car ride rough, the one closest to you facing the engine i replaced with a walker one, could it be faulty cuz since i replaced ive had rough idle and accel randomly.

 

Whoa that was one of the most incoherent statements that I have ever read!

I think what you are trying to say is that your car has been running like **** ever since you replaced an O2 sensor? Bank 1 does correspond to the front, I believe. Someone else can confirm that. Exchange the O2 sensor you bought and get another one. If that still gives you the same problem, swap the other O2 sensor on the front with the new one. If it STILL idles rough - rough idle can also be caused by a bad injector.

Does the car feel gutless?

 

thats what we all thought it was an injector, when i put in a bottle of fuel injector cleaner it runs like ish for the whole tank and then acts kinda normal. but the cel came on again and reads bank 1 O2 sensor, could it be my alternator not givin power since it needs to be replaced?

 

Sorry, it is pretty late right now and your english is now WAY beyond my comprehension. But from what I understood from that last message, I do not think the problem is with your alternator at all. But then again I didn't really understand what you said...

 

do u think my alterator is causing my o2 sensor to act up since its brand new or does the 02 sensor a faulty one?
