1993 Oldsmobile Ciera 93 Cutlass Ciera S 3300. VERY VERY Sl

I have a 1993 Cutlass Ciera S. When I start the car it seems to shudder or shake. When I put it in drive I can put the pedal to the floor and will only go 5-10 mph. While Idling it sometimes dies. I have had the fuel pump, all coil packs, plugs, wires, TPS, Idle Air Control, Fuel pressure regulator, Electronic Spark Control, and ECM replaced. I got nothing. I really need help! I have no idea.
