The idea that you see smoke from both the exhaust and air box is a concern. What color is the smoke from the exhaust? Also, when you say it surges, do you mean it jumps forward and then stalls? If you keep your foot lightly on the throttle to increase RPMs, can you keep it running?
Sorry for so many questions, but I have two more. Have you scanned the computer to see if there are any diagnostic trouble codes? Also, is it possible for you to record what it does and upload it for me to see and hear?
Let me know.
PS: Let me know how much smoke and its color.
