2000 Ford Escort Very rough running

Engine Performance problem
2000 Ford Escort 4 cyl Front Wheel Drive Automatic

My problem on my 2000 escort started out as a rough idle when the car was cold, and every so often it would just start running rough for a few minutes after iy was warmed up. Now it won't hardly stay running at all. I have checked for spark (good) replaced to coil pack, the fuel filter, and the camshaft position sensor with no luck. I just removed the cat converter thinking that had to be the problem, and it will idle a little pretty good now, but runs terribly rough when given any gas at all. If I pull the fuel line from the filter, and hit the key, it will shoot fuel about a foot in the air, so I'm assuming I have plenty of pressure. Any help would be greatly appreciated.
