So, my 2005 CE is throwing a P0171 code (bank 1 lean).
I've replaced the Mass Air Flow sensor, I've had the intake smoke tested and sealed, I've replaced the downstream O2 sensor, I've replaced the upstream Air/Fuel Ration sensor, I've replaced the PCV Valve. It's still throwing the code.
I'm running out of ideas.
