It's plugged in and all the wires look fine. Could the sensor just have gone bad?? I have erased the code and it immediately comes back on along with the P0031 sensor heater code.

Also, anyone notice a little more rev hang with test pipes?? Maybe because of less back pressure? When in gear and I lift off the throttle the revs hang way more than before test pipes. Only other thing I can think of is the a/f sensor is causing it. Its really hesitant at low speeds too.

Anywho.. I found an OE Denso upstream a/f sensor on Amazon for $86+ free shipping. Will install and report back. Hoping the engine light goes away and the car drives normal again.
