The engine keeps jumping!!!

Hey there guys, i keep having this problem when i hit the gas slowly where its about from 1500 to 2500 rpm the car kind of jump and shake the hell out of me, i change the fuel pump today with the fuel filter but still its the same... Any ideas why???
Injectors maybe???
I have m20b20 which recently made it to m20b23
Oh and one more thing, when the engine gets to the right tem and the rpm goes to 800 it kind of starts playing up and down, its not stable most of the times

did you do anything else, like bore the walls, shave the head, rebuild the head, replacing timing chain/belt, vacuum tubing, intake boot, ect.

it sounds like a power balance issue, so anything from poor injector flow to a vacuum leak to weak spark.
