The eBay sensor has a resistor and diode in place of the glass PCB found in the OEM part. Causes rough idle (stalled a few times) and loud pinging. My guess is it overestimates airflow, causing the ECU to inject more fuel than necessary. The old sensor reads 0 all the time, which means the ECU will never overinject (not to the point of detonation, anyway).
