ok, so my car was running weird, and this is what I just found:
http://teamfc3s.org/info/articles/o2sensor.html
In the article, it says that the 02 sensor wire is shielded, and that he tried to fix it with a spade connector, and that this ended up shorting the circuit.
Well, since I bought a racing beat header, I used crimps, and a piece of normal wire to extend the wire back to it's original location.
Well, how bad did I mess up? Will I need to buy another ECU now?
