To address some suggestions- 
 
I have replaced the dist. cap, rotor, and plugs, but not the wires. I have not yet cleaned out the idle control valve or tested the fuel pressure. I have not changed the fuel filter very recently.
 
But would these things be the culprit if my idle problem only exists when the engine is very cold at start-up? 
 
And what about my stumbling/hesitation problem, but only for ten seconds when first accelerating down the road? Related or unrelated to the idle?
 
Thanks and keep the ideas coming.
