Coming to a stop or giving it a little throttle from a stop, the car will sometimes want to stall and does every now and then. My gas mileage has dropped to about 20 mpg and the back of my exhaust is covered in black soot. Some days the car will drive better and then a few days later, the problems will come back. I've brought this up to Mike at MotoEast and he's using my current tune on a few cars as a base map with no issues.

I feel like I have read about this issue more than once on the competitor thread but I do not remember the solution. How does the O-ring look for the MAF? I think swapping it out would be a great place to start. Then checking for leaks.
