Hey guys. I got an Fc few days ago.
While driving normal the car runs great.
However today while turning off a road i revved matched down and got a pretty loud back fire, followed by smoke billowing out the back and all you can smell is gas.
Any ideas of what could be causing this?

 

it also smokes when you get on it?
just no where near as bad when you rev match.

 

TPS Adjustment/check time?

 

I'll look into it thanks
