2002 DII V8 speeds up during cold weather

Multic,
Where are you located? Cold weather should not have any effect on your engines RPM's or idle.
Living in Colorado where we have already at some mid-teen temps, I never experience what you are describing.
Try cleaning yiyr t/body and Idle control solenoid, if you don't know how, send me your number and I'll call you.
Might also make sure your throttle cable is not sticking.

No, in idle state all ok. No big rpms, no extra fuel consumption, etc.
This happens only during the driving and only when weather is cold ...
Now i build "all obd data logger" based on notebook and try to find which parameter is "bad" or "looks strange or unusual" ...

sticking linkage should be considered. There is a throttle body heater plate with small water hose in/out to keep butterfly valve from icing up while open (stuck throttle). You would not want to have that part of the cooling system "bypassed". Cooling layout attached from RAVE service manual, full download below

Cold air is more dense, the more dense the air the more air is being squeezed into your combustion chamber. To prevent running rich with all the air your ECU will put more fuel into the mixture. All internal combustion motors will run better with cooler intake temps. You may have some electrical issue but when it gets cold out it takes a while for your ECU to computate the ideal parameters for new conditions.
You might have some electrical issues going on but all motors will run better and bring RPMs up faster with cooler dense air.
