Default 93 SE Rough Start-up/ Take off

Ok, here'* the situation. When I go to start my car after it has been sitting for a few days, the engine will idle roughly, and almost cut out. The engine will do this for about a minute or two, then smooth out. If I try to pull out of a parking lot or driveway, the engine will reach 2500 rpm, then stop there, and just not be able to push through 2500 rpm for a few seconds, then take right off. If the engine is warmed, she'll take right off, no problem. Does anyone have any ideas, or diagnosis of the problem?

Very intresting..i wonder if there is any stored codes..the Service Engine soon light isnt on is it? If it isn't this doesn't meen there isn't a problem.
My first guesses would be anything tune up wise..spark plugs, wires, and air filter will make a huge diffrence. After that i would take a look at the Idle Air Control Valve (IAC) sometimes it can get dirty and start to clog, this can cause issues like you won't belive..
Check out all the tune up items first.

The check engine light isn't on. I'm in the process of giving her the pre-winter tune up (plugs, wires, filter, etc.) right now, so i after the weekend everthing will be done in that aspect.
