sputtering problem, engine running rough Options

[BlueCeliGT]

So here's the deal...

When she starts up first thing in the morning she runs great. But as the engine warms up it has a rough idle(a bouncing effect) and when i hit the gas it'll sputter then catch but still not at full power. Cleaned the intake filter(aem cold air) changed plug wires and cap(no rotor tho), plugs are a month old and were pulled to have gaps checked. It started after we got a big snowstorm here a few weeks ago so i was thinking possibly a problem in the fuel system but looking for other ideas

Thanks

O.K... The problem is getting worse now I've been off work for a week due to the old Shingles, Very painful lol. My car hasnt moved for a week as a result. When i used it to go to the docs today it started fine, but it wont let me accelerate until i get the revs up fairly high. Also when crusing along the road at 30MPH it started to get really jumpy like it was missing, proper kangarooin down the road, but as soon as i lift the throttle it goes smooth again, or if i floor it after a bit of a splutter it eventually takes off. Does anyone know what this could be or am i doomed to just wait for it to completly die befor i find out what is causing this erratic behaviour?? Please help me, Waa!!! i love this car but its treating me badly lol
