I'm not a master tech but from experience to check my spark, fuel and air, you could have a simple vacuum line pinched or split for all you know. A good start would be to check all the stuff you replaced recently

So I did a little of ecu work today and got it to read code 55 which is (settings OK) and my car is still sputtering. It's not at a certain rpm now it's just sputtering at random I'm thinking it has something to do with fuel? Maybe injectors? Any inputs?

While the car is running try unplugging injectors 1 @ a time... If you unplug 1 and the sputter/idle doesn't change then you could have a dead injector. If it gets worse, that injector is working fine.

The idle of the car is fine it's only sputtering when I try to floor it, if I try to ease into it also it's fine just when I try to floor it the car starts to act like I have some sort of anti lag on it and my buddies even said it shot a flame when it was sputtering

I've had this similar problem with the previous motor ( sohc ) and all I did was clean out gunk from top of injectors and it revved all the way up no break ups

Update: checked the fuel pump and tank and found a lot of sandish material inside

Flush the tank, check fuel pump voltage to see if it's any good, check your fuel filter, if the filter did its job then you're gonna need to flush the fuel line and replace the filter again

Bro is your problem still going on I recommend changing all your fuel components check your fuel filter in the engine bay & see if it's filled with that

Yea I fixed the issue my injectors were never messed up, turns out the sand substance in my fuel tank was old gas so I took out the fuel tank and scraped off all the sand stuff from the walls and off the baffle then I hosed it down and scrubbed it all down to make sure I got most of it out and finally 4 fuel filters later the car is running fine
