Engine code P0172

Hi,

I am sorry for previous posting of engine code trouble.
I went to Autozone and got the code read and they told me that the engine is running too rich?

I wasn't given the code but the only rich code seems:

P0172 Fuel injection system rich

Guy asked me what gasoline I use. I use premium, but don't think that'd be the cause.

I recently changed the fuel filter, and thought it was clogged, but If it was clogged, it would run lean, not rich, right? Anyway, any help will be appreciated.

Thanks again,

Go back to auto zone and get actual code number. Don't settle for counter monkey's summary of 'too rich'.

Sorry for the lack of info. This was on a 2001 Pathfinder LE with VQ35DE.

Sorry again,

I realize that. I only posted because I was hoping that someone with knowledge of VQ35DE would maybe give me some ideas.

you'd have been better off asking in the 6th gen or 5th gen forum.
the code only means you're running rich on bank 1.
nothing more nothing less.
now as to waht is causing the code, you have to start diagnosing.
