Hi All,

An old problem of mine is now haunting me in the winter months. I've checked around the forums but it looks like people are having problem with going lean when they blip their throttle.

My problem at the moment is opposite that. When I blip my throttle, I get fuel, but then right after, for a split second, the fuel cuts off completely- AFR= 18.

This problem is only really noticeable when the car isn't fully warmed up. So when the car is at operating temperature, it runs like stock. However, if its 1 degree below operating temperature, this problem occurs.

I've posted my logs for your viewing pleasure.
