Also, something that's relevant to mention. This car is manual transmission.

There's a problem though, the wiring on my new 02 sensor has 2 white wires, a black wire and a gray wire. The old 02 sensor has 2 black wires, a blue wire and a white wire. I havn't been able to find any wiring diagrams that indicate voltage on the 02 sensor wiring that would help me figure out which wire would go where...I'm kind of at a loss here. I'm wondering if they jacked the wiring on the 02 sensor and it's sending rump roast backwards readings to the ECU that's causing it to remain in open loop?


the 2 white wires will go to were the 2 black wires are (heater circuit)  The other 2.......try them one way and if it throws a code immediately switch them to the other way.
