ok so a couple days ago I was trying to figure out what was wrong with my car not being able to idle and it would have very bad lack of acceleration, so assuming it was a fuel issue I unbolted my fuel rail so i could see if the injectors were working properly, and I found out that the injector for #4 cylinder wasnt spitting fuel but #1-3 were. so i changed out the injector and still no solution so i changed my fuel filter (my fuel pump is new btw) and tested my injector plugs with that light you can rent from an autoparts store, all plugs flashed. now last night i thought id check them out again so i did and found out #3 and #4 cylinder injectors weren't firing. checked again today just now and only #4 cylinder injector is spitting.

im so confused on whats going on right now, could this be an ecu issue? please help.
