Backstory:
I've been fighting a progressively worsening problem of my car feeling like it's missing significantly whenever there is load on the engine. Going up hills, accelerating through the gears, etc. It has gotten very bad recently, and is not very drivable when it's acting up. However, sometimes you can start it up and drive it and it will just miss a little and is still driveable.

Today I pulled the injectors to look at the spray pattern and when I was testing them, sometimes they would spray fine and other times they would spray in pulses, which would explain why the car acts the way it does. All injectors would pulse in unison. The fuel pumps were not pulsing or anything and I think whatever is causing that is the root of the car's problem. Is something getting stuck in the fuel distributor? I have had both fuel pumps and fuel filter changed in the last year so I think they're fine.

Any thoughts?
