2002 Sante Fe, 2.7 300+Km,
I am stumped, I had P0171 & P0174 codes show up indicating the oxygen sensors detected a lean condition in Bank 1 and Bank 2. The car was using an excessive amount of fuel so since I have never changed the O2 Sensors I figured it was a bad sensor.
Changed out Bank 1 upper sensor, cleared the codes and they both returned after about 100km... Changed the Bank 2 Upper sensor and to eliminate it, thought why not change the fuel filter at the same time... After the filter was changed, the Sante Fe was difficult to start and started backfiring through the intake and has no power. Checked all the connections, checked fuel flow (not Pressure) and still no joy. Checked the Mass Air Flow Sensor, it is clean. (Not sure what it is supposed to read on the meter.) Checked the Throttle Position sensor and it gives a couple funky jumps when going through the range but there was absolutely nothing wrong with the power or acceleration before this...
Went from a car that ran well but used fuel to a large ornament... Car Starts, Idles, but can't accelerate, and has NO Power, nothing. I am looking for suggestions or ideas...
