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???

Technically the GT has been around for a very long time, and 95 is not the first year GT for the 6th Gen. 94 is. Secondly your engine is not G3-SE, it is 3S-GE.

Now that that is all cleared up, have you tried resetting the ECU? I was having the same problem a year or so ago and it was from when I disconnected the battery and did not give the ECU time to relearn.

Basically try unhooking your battery. Let it sit for a while, then come back and reconnect it. Start the car and let it sit. Take it for a drive after sitting for a while. Does it behave better?
