The idle valve is the most common problem for hard starting in cold weather. I would recommend having it removed and inspected for contamination. Sometimes they can be cleaned out. If it has heavy carbon buildup, you may have to replace it. (if the idle valve is removed, the shutter inside should easily move when you rotate it from side to side and you can also look at it with a flashlight for a visual inspection.

A couple of possible problems, low compression on one or more cylinders, possibly a burned valve, possible headgasket leaks, have the compression tested and checked for a headgasket leak, both of these conditions would cause a rough idle and then seem to run normally when warmed up.

99 ford ranger, idles rough till it warms up,then runs good. Hard to start after it gets hot, it acts as if it is starved for fuel. Once it does crank it runs fine.

First thought: Check the idle air control valve, or whatever its Ford equivalent is. Sometimes these start to stick and cause the rough early idle that smooths out later.

My Mazda starts rough and idles real rough with black smoke and smell of gas after warm runs great

Dear Smoker.......Sounds to a trained ear that this little guy is gonna need a fuel pressure regulator. It is basically dumping an excessive amount of fuel with the black smoke and all and once it gets warmed up it runs a little better cause it's out of the closed loop cycle. Check the fuel pressure regulator...pull the vacuum line off of it and if you can smell gas or see gas drippin out....that regulator is junk!!! The pressure regulator is on the fuel rail on top of the motor by the way...this should cure your woes.....if not..please get back to me... I HOPE I COULD HELP!!!
