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

I feel your pain, i have the same problem.

Things i replaced:

Airfilter, TimingBelt complete kit, Ignition Wires, Spark Plugs, Coolant with flush, Thermostat, and PCV Valve.

Next to try will be Throttle Sensor, Fuel Filter, and O2 Sensors both of them.

Any Advice?
