Has anyone noticed that when its really cold your 5.0 starts and runs rough. It almost smells like its running super rich like its dumping too much gas into the motor. Has anyone else experienced that? I know that if i just give it a few revs it blows white smoke a little bit but then it clears up and runs like a champ. Is it just running rich because it's cold? It has only done it when its cold, but not every time.

The coldest temperature that I've driven my Mustang in is -16. I didn't notice what you are describing regarding the engine. White puffs out of the exhaust when cold are normal though.

Ahhh yes. That should have been my first question. If it is tuned then it's another can of worms altogether. Good luck man.
