Car problems when cold?

Hi,

I have a 1993 Kia Pride 1.1, and when cold the car is a pain. I'll start it up from cold, the choke will come on as normal. Then once choke goes off, the car will go to die (I'll have to step on the acceleration a little otherwise it does die). Then sometimes when I do go to step on the accelerator to keep it running, it like misses then comes back to life. Also when the car is cold and doing this, if I put my foot slowly down on the accelerator pedal, when it gets to about 1/4 of the way it misses and goes to cut out, if I carry on again it will come back to life. The problem is that when I try to drive away when the car is cold, or when the choke has gone off, the car kangeroo's like mad for a few minutes and it's somewhat annoying. The idle is also real lumpy when cold, it's not level and keeps dipping etc. Still the same when idle is turned up aswell. I understand that the car is old, but I dont think this is normal right?

When the car warms up properly, it's fine. However, the idle is still lumpy and still remains un-level. This is what lead me to think that it could be an intake leak causing the problem, what do you think?

I've cleaned the plugs, ran through some fuel treatment additive and changed the fuel filter - No changes, still have this problem. Any help please? Thank You.
