After having replaced a bad EGR Valve and pressure sensor, my Explorer is now givng me a P0174 (System too lean - left cylinder bank).
Someone has told me that this could mean an O2 sensor has gone bad. Does anyone know how to find out which sensor would be bad? Or do I just need to pick and choose and start replacing them?
Thanks for any info!
