YJ Rough Idle, Sputter upon Acceleration, Smell gas, Cant even drive it!!

Alrighty. As the title says. My 1991 Jeep YJ 2.5l 4cyl Fuel Injected. Wont run right. She sputters along.. Rough idle. Stalls out. Smell of gas coming from her. Heres what i've done so far.

Plugs
Wires
Cap
Rotor
Fuel Injectors
Fuel Filter
Fuel Pump
Map Sensor
Throttle Position Sensor
Coil

Also seafoamed the engine and used drygas.

I'm really stumped. It use to do it occasionally. Now i cant even drive her a few feet without the sputter kicking in. I'm at a loss. I'm puzzled and so are my friends. Any help would be greatful. I really need to get her running good again.
