I have a High Flow Converter on my car and the MIL came on. I know the reason it came on is that I intsalled the converter. I was wondering if my car will get messed up by driving with it like that? I know that if I don't get it fixed then I will not know if the MIL comes on for any other reason. I was wondering if and O2 Simulator is worth $50?
It's recommended when the cat is changed that the o2 sensors be changed as well. You can leave it... but I wouldn't recommend it.. especially if you have inspection coming up.
