04 cavalier I just bought hasn't got a cat.
Do I:
A) Put a cat on it so we can all breath a little better?
B) I heard something about a simulator, put on of these on it?
Any info would be great with this option I don't know where to get one.
C) ignore it, who cares if the lights on.
Does it still have the second O2 sensor? It could be right after where the cat would be. If so you can do a manual O2 sim that cost about $5 to make. If you do a search in the performance section you will find info on it. I also have one that I no longer need.
