Hey there, thanks for writing in about your 2006 Mazda6. Check the air intake filter for blockage in the pipe or before the filter inlet. If you have no air getting in, then you will get excessive fuel. If the mass air flow sensor is bad you would get too much fuel also. If no block is found, then replace the mass air flow sensor. To have all of these problems addressed, have a certified technician, such as one from YourMechanic inspect your stalling, smoke issue, and oil leak in order to make an accurate diagnosis and move forward with the appropriate repairs.
