my question had nothing to do with driving a car hard cold, it has everything to do with fueling adjustment when the engine is in different coolant temps.

You tuner needs to tune the acceleration fuel settings. If the base settings are correct, you could try to change the accel tp sensitivity for instance and see if it makes a difference.

I think I may have an idea on what the problem is,,,,I went out Last night,and she wouldn't start,with light this morning,I went out and wiggled the wires to the CPS,and Map Sensor,,,not sure which wiggle did the trick,,but she started,,could this have some bearing on the problem ??,,,unsure connection ?
