I have a 1993 se, I was told it needed a new cat, I personally dont have that much money to buy a new cat and was looking into a used one which the person ssaid it help him pass smog in janaruy then took it off to add a test pipe. He said the stock cat was off a 1992 and said there was no o2 senor plus. I was wondering will the o2 senor plug effect me at all? Can I just plug in the senor i have?
