ACK! If I was as rich as my car...

I'd be looking at buying a new caviar powered jet boat with 50 high end strippers as crew.

Since the engine swap, the car has been running real rich, black smoke, black crap on the bumper and it will bring a tear to your eye. It always ran kind of rich but I think since the GT40 heads don't have thermactor provisions, it's worse...

The computer is throwing left and right bank codes (O2), I didn't change them yet but the new sensors are purchased. My buddy (who's a genius mechanic) thinks it's something mechanical like my fuel pressure or something. I'm starting to wonder (on his thought) that maybe the intake is leaking air or something?

Can O2 sensors really make things this rich? Seriously?

was it only after the head install? or did you change multiple things at once?

We changed the whole engine lol... original spark plugs showed no signs of a rich condition. It always ran rich though, could be the stupid FMU that's not adjusted right. Going to change the O2's today and check the mechanicals.

Thanks
