Bad oxygen sensor? Or something else?
I have a 2004 Honda Accord DX, I have gotten a P0171 error code(Fuel System Lean), and P0131 (o2 Circuit Short to Ground).
My car runs fine once its started and I haven't noticed any gas mileage problems, but when I start it its a rough start and takes 3-8 secs to turn over.\
From my understanding this can't be the O2 sensor because it is in play when starting the engine.
I have been looking everywhere online and only thing i could find at all is to maybe check the some other sensors?
Can these sensor be check with a multi-meter? If so which ones and where? I check the battery and it is fine. Some type of fuel sensor?
I don't want to waste money on buying a oxygen sensor if this really inst the case.
ALSO: I did mess with a starting coil fuse before this happen. But would this be related? If so how come i'm only getting o2 sensor errors?
I would check for vacuum leaks. A bad O2 usually makes the car run rich(worse mpg).

- Does a 99 Honda CR-V have and up and downstream oxygen sensors? My check engine light came on, took it in to O'Reily's, and they say I need a new O2 sensor. They can't tell me if it is up or downstream though so I'm wondering if the 99 CR-V only has one.
