still got p0171 code...wtf

 

I would change the upstream o2 sensor...

Per the list I posted previously..
Bank 1 Sensor 1 (Its the one before the cat)

Or pull it off the car and take it in to be tested...
before you spend extra money on a new one... (there expensive)

Is that the only code that's showing up?

 

I did change that one with a delphi one a few weeks ago,the one i took was grey looking ..not to lean..

 

can you check them out of the car?

 

Yes with meter..
By amps/voltage

 

tell me more...

 

Heres a link that will better describe the code.

OBD-II DTC: P0171 System Too Lean (Bank 1) <-------- Clicky

 

Thanks,thats a good site..if I take the 02 back out an look will that tell me anything,,ya know if its grey or black/white..

 

Its my experience
They/it can only be tested by using a meter.
Unfortunately

 

Do you not have any way of reading live data?
