As the title states I think my car is running rich after I have had my new Crow Stage 3 cam and custom tune. When idling I can smell the petrol fumes and before I didn't have any smell coming into the cabin.
Also I when idling I have seen condensation come out of the exhaust with black soot (unburnt fuel?) Also from JMM I was told I need a new O2 sensor as it doesn't start responding until the car is up to temp. I have purchased a new sensor, just haven't put it in yet. Is this a contributing issue as well? I have attached the dyno sheet below for anyone knows about AFR. Do I need to go back to JMM and say my car is running rich? I am going though heaps more juice than I use to. I understand I have put a bigger cam in with a custom tune but wasn't expecting the huge difference in fuel consumption.
