Car will not accelerate past 50mph. It is at an auto mechanic shop now and they cannot diagnose the problem. They have tested the catalytic converter, torque converter, throttle position sensor, crankshaft sensor, and the coil pack. They have had the car for over a week now.

Have they checked for vacuum leaks on or around the intake? Have they tested fuel pump pressure to ensure it is within the manufacturer's specs?

Thanks for answering!!! They have checked all hoses and the fuel pump. They were checking the fuel injectors next. I haven't heard anything back yet.
