CIS-e runs like crap after installing new fuel filter

So I put the new fuel filter in, not because it needed it, but because I just bought the car and figured it would be good idea. Now it runs like crap though. Mostly when I first start it if I touch the gas at all it will die. With great effort I can actually get it moving, but then it stutters terribly. After it's a bit warmer it doesn't seem to do it as much.
It was running almost flawlessly until I tried to make it run better. All I've changed is the spark plugs and the fuel filter (and the sensor on the oil filter housing). I'm pretty sure the filter is installed in the correct direction, with the arrow pointing towards the front of the car (air filter is on driver's side).
Open to any suggestions.

it definately sounds like after you replaced the filter, the car is no longer getting the gas. Its possible some debris entered the fuel dizzy? (hope not) or the fuel filter is simply no good even though it was new? take it out again, and try to blow thru it, it should be extremely unrestrictive. any lines get kinked? Defective check valve? The filter should only go in one way, AFAIK the bolts are of different sizes. I highly recommend the large fuel filter over the small dinky one. I had that small one in my car, and it did the same thing you describe, could barely get the car to go, replaced it, and all was good.
Cheers!

What would I have to do if it got in the dizzy?
I'm pretty sure the bolts are different sized too. I wasn't too worried about it being in backwards. Where do I get the large fuel filter?

Well if it got into the dizzy, chances are it made it all the way into the injectors, in that case, you are out to get new ones. http://****************.com/smile/emthdown.gif But thats an extreme case, first check the fuel filter you installed, then your lines, to see whats goin on there. I suspect its a bent or kinked line, or the fuel filter is crap.

So I just went out and pulled the filter back off. I held it so the arrows were facing down and let all of the fuel run out. Then I put a rubber glove over the end facing up (arrows still down), poked a hole in it and blew through it. It blew about twice as much fuel through it as what originally came out just by gravity. Is that normal?
How unrestrictive is "unrestrictive"? When I was blowing through it there was some restriction, but not more than I had the ability to blow through. It felt like blowing through a hose that has a ball of hair in it (don't ask me why that particular example came to mind).

I just went out and blew air through the old filter and found that it wasn't any less restrictive than the new one so I don't think that can be it.
Where do I get the larger filter you spoke of? What is it from? Part #?

Large or small, a NEW fuel filter shoundnt make your car not run. I would look at something else then, if you ruled out the filter, something that you may have bumped off, or whatnot, while you were changing it?
