If I take the key out some dash lights stay on in the same area around the check engine and my power windows will still work for some reason.

Are you getting 12 to the starter? Are you getting 12v to the starter signal wire when you key over? First two places I'd check.

Im having a misfire issue at idle and noticed that when it starts missing, the o2 stays pegged at 0 volts. My afr goes full lean as well. Its not a constant misfire either, just a hiccup if you will.

The o2 should always 'sweep' back and forth, regardless of closed or open loop. Now with that said, obviously only in closed loop operation does the ECU utilize the O2 for actual air fuel

With that considered, at idle, the ECU does not utilize o2 sensor, as it's in open loop. Even if warm, at idle, (if the TPS shows off) it doesn't use the o2 for anything.

As far as activity, You should see it swing back and forth pretty actively...it it only swings 5 or 10 times a minute then the o2 is starting to fail, and closed loop operation will suffer.

With all of this considered, you can also run the car in total open loop by disconnecting the o2 sensor. May be worth it just to try something.

Thanks

Whatever you want to pay. It's up for the owner to decide if your offer is what they want to sell it for.

Agreed
