Erratic Idling and not consistent acceleration.

Erratic Idling and not consistent acceleration.
Pretty much what the title says. I can't get an smooth idle and when I'm revving it up on low RPMS I can't do it smoothly. It continuously jumps up and down.
Before this it didn't even idle, it just stalled. Got some error codes on "cylinder misfire 1" that I've fixed changing the 2 plugs from the first rotor and now I have this. It's better than before that's for sure, at least now it doesn't stall. Also after revving up and letting go of the pedal I get some popping noises, maybe clogged cat?
The engine is rebuilt and it doesn't have more than 10k Km. And the compression test that I have before I bought it 3 months ago says that it's good. Alternator is charging at 13.80, battery it's 6 months old. The ECU is modified to add more oil to the mixture for reliability. The oil I'm using is 20w50.
Any help for fixing this? Maybe 4 new plugs, coils? Dirty MAF?
U can hear it on this video. I am revving it without moving the foot on the accelerator.

i always replace all plugs, wires, coils together. i would start with the easy cheap stuff like cleaning the maf, cleaning the ess and resetting it with the 20 brake stomp

I was thinking on a BHR coils set, an Iridium NGK plugs and a MSD wires. The only thing about them is that i'll likely have to wait 1-2 months for them bcs of shipping to EU and all.

never give up
Why don't you try the aem ign a1 kit. You can find it in EU. Comes with harness and msd wires. All you need is a bracket to mount them.

I've changed the cat to an empty one, cleaned MAF and ESS and the 20 brake stomp. It improved a little bit but it's still irregular. So I think that the next thing should be plugs/coils/wires

I've let it run for about 10 min on idle and it finally ended very similar to the video. It's weird that when you go above 3k rpm the problem dissapears and the acceleration is smooth

Check and clean all your grounds too. I’m happy with my Bennett setup for coils and wires. Very affordable and his billet aluminum bracket is top notch.
