Engine idles rough and dies when cold.

My 05 Mountainer will idle very rough when started up cold. It also will die sometime. It only does this on a cold start. I replaced the plugs and wires a month ago and that didnt help. (125000 miles it needed it done anyway). What could be causing my problem?

Ill try cleaning the sensors first. If it was a bad coil wouldnt it idle rough all the time?
