I was in the tuning section and asked about a power issue I've noticed in my 2001 2.2L4. There's a substantial drop in power as soon as the ECM goes into closed loop mode. I have a header that moved the upstream (Bank 1 Sensor 1) O2 sensor down a little bit, making the wire too short. I can assure everyone that I soldered the wires together correctly as my scanner shows a good signal from it. I'm told that I just need to convert to a heated sensor, probably because the sensor is located further downstream. How do I go about doing this and where can I find one?
