Re: o2 wiring problem?
The O2 sensor you bought is probably just a crappy one wire O2 sensor, so one wire is signal and the other is ground. The O2 you have in there already (the 4 wire) is a heated O2 sensor, which generally works a lot better. I would really spend the money and get a decent replacement for the stock one, because it is one of the most important sensors for proper engine operation. Usually cheap universal replacement O2 sensors are absolute garbage and don't work very well.

If the ECU is looking for a heated O2 sensor, you'll probably get a heater circuit CEL. You should really buy the right replacement for that if you want everything to work properly.
