Default Slow/Sluggish Acceleration, Periodic Chugging

I have a 2002 Saturn SL1, 180k Miles. It's my first car. I'm no master mechanic, but i know a bit about cars. Mainly basic regular maintenance. I recently did a fair amount of work on it because it sat for almost a year in my dad's front yard. The work included:

Steering Column Replacement
Security Bypass ("Re-Learn")
Tire Rotation
Oil and Filter Change
Brake Bleeding and Fluid Top Off
Exhaust Repair

After all of these things were done, i started her up and took her for a test drive. The issue that arose, was that my car accelerates painfully slow, even with the accelerator all the way to the floor, and sometimes chugs and lurches. I tried letting the car warm up a little before driving it, i tried shifting through all the gears and letting it idle while in each gear, and it's doing the same thing. Only once or twice has it actually accelerated at a normal rate, but then it chugs and begins to accelerate really slow again. My brother, my dad, and myself all came up with the following possible diagnoses:

-Bad/Faulty Fuel Pump

-Poor Fuel Pressure

-Not enough air getting to the engine (The engine cant breathe)

-Throttle Position Sensor

-Bad Timing Belt

-It's just old, and sat for too long, and needs to be driven for a while to get used to being "alive" again.

If anyone has any possible answers to why my car is doing this, PLEASE HELP. I just want to be able to drive my car and not have any significant problems.
