I know that's stuck open a bit, but that's not the issue. The air coming into the air cleaner is SO COLD that if freezes the moisture in the crank case vapor and forms ice around the edge of the MAF sensor plate jamming it in it's partial throttle position, and when I let off the throttle, the plate is still open a bit, just enough to flood the engine when Idle position is reached. This will only occur at operating temp and only while driving.
