My car won't start but there is no error code provided, injectors are clean, ECM signal is negative and there is spark in every spark plug. What else should I check?

It started with jerks while driving; when starting gold y vibrates and then it normalizes. While driving it losed power as if choking a little, but now it got worse. It chokes while accelerating and sounds as if exploding, when I let go it keeps driving; if I accelerate again it does the same but it doesn't stall. If I turn it off for 5 seconds it works for 10 minutes and then it fails again. I alreadi cleaned the injectors, changed spark plugs, air filter, fuel filter, fuel pump, coils and their sensors. I've already had this problem for a year and they can't solve it, yesterday I scanned it and had air sensor error, but changing it didn't fix it.

I have changed the coil-packs, wires, plugs, egr value, & sensor. I have cleaned the injectors on #1 & #2 changed them around. After doing all this I'm not getting any fire in #2 and the above symptoms
I don't know what else to do.

keep having an issue with cylinder 4 miss fire. I have already replaced all eight (8) spark plugs and the coil pack for that particular cylinder. I have also put multiple bottles of fuel injector cleaner in, it goes away for a little bit then comes right back. What could the issue be?
