I had a exhaust leak but I just had my header all welded up so now all is fine and I don't have the rotten egg smell from the exhaust so I don't think it's the cat. I've checked the fuel injectors and they are ticking and when I pull them off individually it will die down on each plug.
Checked the egr vacuum also and it was good as well
