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

Hey All, I also have a 95 'First year GT' and my car also has these same really annoying symptoms. I've had them for around 6 months now and can't get to the bottem of things. The car does approx 100 miles per day on the M-way, and currently has 113K miles on the clock. I've tried to cure the symptoms for ages but nobody seems to be able to help!! My symptoms are... Starts fine all the time, as soon as i set off the car seems jumpy, if i put the clutch in the idle seems to hunt for the correct idle, somtimes gets it so wrong it stalls. This can happen any time, wether hot or cold. I rekon i have about half the power i used to, and the car seems to be becoming sensitive to cold weather. Fuel consumption is up too. No obvious oil burning or leaks of any kind, no engine wear noises either, it just runs crap for a laugh i think. The only thing i can think of that i havnt tried yet is o2 sensors. Engine is a G3-SE, no fault codes either... CAN ANYONE PLEASE HELP US???

Cheers :-)

P.S should there be a temp sensor in a hole in the side of my air box? Cos there has never been one there and when i got the car i just blocked up the hole???

I thought the Gt was introduced in 94!There is supposed to be a sensor in the airbox by the way.

Anyway I have a 94 M plate 2.0 GT and I think I have the 3S GE engine.
I have a problem with the idle which is higher than I would like at about 1500 when cold and the car runs rough till about 2000 RPM.

If the car is left to idle it warms up and the temp guage shows the needle at halfway the revs will drop down to around 800 rpm. if I go for a blast down the motorway the temp guage drops right down and the revs come back up to about 1200 RPM. it all gets worse in cold weather and the car takes an age to warm up if the outside temp is less than about 8 degrees


I thought I'd change the thermostat but when I took the bit of metal off where the top hose meets the block there was no stat??? which is a shame because I bought one of EBAY

I thought I had a dodgy sensor but they have all been swapped and tested and supposedly they are OK.

So I'm stuck as well. The car goes well normally i.e. when your on an open road and the revs are above 2000rpm.
