Question about 2004 Dodge Ram 2500
A little more info would help, but I'll try anyway. I believe that you either blew a head gasket or cracked the head. If the smoke had a bluish tint or smells like anti-freeze or has a 'sweet' smell, it's a 99% probability of this.
If it's grey or black smoke, with a heavy burnt smell, it could be anything from a head gasket to a simple oil leak that is dripping onto a hot exhaust. If it's a leak, you may lose very little oil, not really noticeable on the dip stick. (You'd be suprised how much smoke can come from just a little oil).
The fact that it's running differently also points to a head gasket and/or cracked head. If this is the case you now have less compression in atleast 1 cylinder which will cause misfires, loss of power, rough idle,etc.
As far as weather changes go, the cooler an engine runs, the better it runs due to a more perfect air/fuel ratio (14.7 air to 1 part fuel is the perfect balance, or "stoichyometric").
First of all, I wouldn't even start it until it's repaired as you may (and probably would) do more damage. What to look for: Is your coolant level low?; Is there water in the oil or oil in the coolant?;
Is there anti-freeze or oil visibly leaking?
A compression test most likely will be required to check the head(s) and head gasket(s). I would find a competent mechanic to look at it ASAP as there's only so much that can be diagnosed without physically seeing it. If you can, let me know about any leaks, coolant and oil levels, color and smell of smoke, etc. and maybe I can pinpoint the problem further.
If it is a head gasket, make sure the mechanic checks the head(s) for cracks as well or the head gasket may be for nothing. Good luck!
