Every morning I cold start my car and it idles extremely rough sometimes to the point of stalling until it becomes warm. I have kept up with all normal maintenance including a oil change less than 100km ago. I have ran premium fuel for the last 6 months and I am now really stuck for answers? any help would be appreciated!!

List all maintenance and modifications
Pull engine codes and post here
How many miles on the car?

The car has 131,000km

Oil change 100km ago
New serpentine bent 300km ago
Timing adjusted 2 months ago
New distributor cap and rotor 2 months ago
Spark plugs at 105,000km

As for engine mods only MSD plug wires and a cold air intake
 
Still need those codes: KOER and KOEO

It could be something as simple as a sensor out of range or maybe even a vacuum leak somewhere (I might suspect a TAB or TAD solenoid, for instance).
