fuel injection system too rich, bank 1...

what am i looking at here? O2 sensor or something else?

I'm not too familiar with codes, other than deleting the rear o2's on my camaro

 

Could be your MAF sensor. Hang on, let me look in my manual.

Dang, looks like you will need a Consult machine or a scanner that can read your MAF sensor readings.

Here are the possibilities:

Possible Cause

I Heated oxygen sensor 1 (front)
I Injectors
I Exhaust gas leaks
I Incorrect fuel pressure
I Mass air flow sensor

 

yeah, i searched after posting....kind of did that in the wrong order

does it make a difference that i can smell a bit of fuel at start up?

 

Could be a leaking injector.

 

one year later bump...the car is missing pretty bad now, i've put off really doing anything about the CEL as it came on intermittently

cleaned the maf sensor, helped for what seemed a few miles, then back to more missing (especially down low)...at start up, the car has a hard time idling and sometimes even dies

what o2 sensors are people running? would it be worth it to change all 4?
