Hey guys I have a 2009 Mazdaspeed 3 that is currently stage 2 FBO and I was driving today and had a cloud of white smoke out of my exhaust on deceleration. I thought it was my head gasket and which I thought may have allowed some coolant to get into the cylinder. And now on my Cobb tuner I have codes for the fuel system being to rich at idle and at off idle. If you have any suggestions plz let me know Or call me to help me out... (435)-896-7465
Not sure what step to take next.
