symptoms on cracket header
I think I have a cracked header and possibly a bad 02 sensor. Any common symptoms that go with these. One symptom I have is that after letting the xj sit and idle it seems to almost flood itself. I have to rev it up and clear it out before it will go will. Thanks

A cracked header can cause the 02 sensor to think it is running lean when in fact it is fine,but it will increase the fuel supply depending on how big the leak is,I have had leaks that did not cause any issues but they can.
