Stumble at 2.5k rpm

[llamaking122]

Even though i am leaking oil like BP i am still getting a stumble. I replaced the FPR and it still happens. its pretty solid from idle to 2k then it stumbles then it goes ok again. And it kinda hiccups

If this helps when i replaced the FPR they couldnt find the washer i had. it had like a rubber insert in the middle so i just used a crush washer.

Try swapping out your ECU if you can. I had a stumbling issue , tried replacing MAF, coils, DIS, spark plugs, but it ended up being the ECU. Mine was bad from idle to 2500, but after 2500 it was like someone flipped a switch and the engine ran great.

Mine also Idles wierd. You start it and its fine idles 600 or so and you hit the gas and it goes to 1700 then you put it in gear and its fine again.
