Winter fuel economy/power

I agree about the running poorly when cold, but I think that you do use more gas while warming up (although it is probably easier on the engine).

I am curious if more of you noticed a similar trend from summer to winter and if you found a good explanation or reason for it (other than the air being more dense and causing more drag at highway speeds or the required warmup time).

I am especially interested in other NA owners power numbers with varying temperature.

I'm with Fidelity.

Could it be that the car is overcooling? THe car reaches operating temps, fan comes on and the COLD air just drops temps too much and runs rich?

I notice the NA drive badly when cold....it seems to run perfect when fully warm but off when it's still cold.
