Question about 2004 Kia Sorento
Bank 1 runs lean bank2 rich, fuel pressure key on is 50psi. no codes stored . checked fuel injectors, 16 ohms and all drop same ammount of fuel when doing a manually injector drop test with special tool. timing belt installed correctly with marks aligned. Changed o2 sensors bank 1 sensor1 and swap with bank 2 sensor 1 no change. If spray choke cleaner in throttle body o2 counts will increase above 450mv if you spay alot. normal condition the o2 count will stay close to 0mv bank1 sensor 1 and2. Changed both convertors , know engine is tour down to the crankshaft sensor. Should i replace it or look a something else?
Might be going super simple here but from what you have said have you checked the wiring on your sensors? If you know that one works and you swap it and its not working its very possible the wires farther up are shorted or burned somewhere.
