Engine fails when accelerating

Hi
I've been trying to bring my car back to life
but it's having so much trouble and i really
don't know what to do now, i've tried
"everything". The engine stalls when i
accelerate. It idles fine. At first when i started
it this summer it sounded like it had bad
injectors and that it was running on 3
cylinders, then the more i was working on it,
the worst it was getting. Eventually it just
stopped even starting. I tried the spark plugs,
injectors, tps sensor, fuel pump, fuel filter,
compression (well that test i'd have to redo it i
missed one step), the battery (obviously).... i
don't know what to do now. Idk if it's
important, but it was a/t at first i swapped it
for a m/t. Now the car starts (it's cold out now)
but the engine stalls when i accelerate more
than 50% of the pedal.
H e l p please thanksss
