Sounds like it just is not getting enough fuel when cold. Try using a bottle of injector cleaner from the Dodge dealer. Make sure it shows naptha on the label and do NOT get any on the paint.
If that doesn't fix it be alert to temporary rough idle when stopping at stoplights. That will indicate you will need to have it scanned.

I'm having the same problems actually. Mine started with the transmission line popping off and spilling all of my fluid on the highway. Fun times and long story heh...anyhow, I believe that there is a special code reader for the p-0700 issues.
Does your car make a high pitched "eeeeeeeeeeeeeeeeeeeeeeeeeee" sound when you turn your key on, without the engine started?

Potential Symptoms
Symptoms of a P0118 could include:
* Very poor fuel economy
* A no start condition
* Vehicle may start, but run very poorly, blowing black smoke, running very rough and misfiring
* Illumination of MIL
EGR valve
Usually a fault in the control circuit, will leave no noticeable symptoms other than the Malfunction Indicator Lamp (MIL) illumination. However, if the EGR control solenoid
is stuck open due to debris, etc. the code may be accompanied by misfire under acceleration, rough idle, or engine dying altogether.
