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

So

This gets a little bit interesting, to me at least.

There IS a check mode, even with OBDII, which probably explains why you don't have a CEL. To get some of the codes the ECU still needs to be put in the check mode, it isn't in it all the time like the newer OBDII.

The problem is, the BGB only lists the procedure for the scan tool. It has no mention of jumping TE2 and E1.
However, as long as you still have a TE2 terminal in your DLC1, I'm pretty sure that will put the ECU in check mode.

But, I CANNOT guarantee doing this won't cause a problem.
Understand there is nothing in the BGB specifically for this year about it.
I'm going on what I know about previous stuff, and making an educated guess.......
