when it's very cold outside. Have noticed it with a full tank of gas (very cold outside) and with an almost empty tank of gas (very cold outside). Took it to the dealer and they kept it overnight outside and tried to replicate the problem. Of course, you all know that it will not do it for them. They also pressure tested something relating to the fuel system and could find nothing wrong either. The other day, 15 degree range and it's doing it again. Anyone experiencing something like this at all? :help: :help: :help: All the best, Mark in N.W. Indiana.
