I FINALLY have the car running again, so glad about that, but my O2 sensors are bad, causing a rough idle. My question is, is this all that bad O2 sensors, cause?

btw, I have a 93 T/A.

Where can I buy new O2 sensors?

And can I splice the wires to install the new one or do I replace the whole wire/sensor?

 

You get a new harness and plug when you buy new sensors.

You can get them from the dealership. I got mine for like 50 bucks i think. They cause stumbling and a decrease in gas mileage. Yes they do come with the wires and plug, so no splicing needed. Oh and it takes a 3/4 in wrench. I went to autozone and they loaned a special socket to me that had a place for the wire to come through and everything, for FREE!! All in all it only took me like 15 minutes.
