2021 Mustang GT "injector cut" issue. Help please!

[5.0_5.0]

Hello! I am hoping someone here could offer some advice. My 2021 Mustang GT has been giving me erratic STFT readings. Sometimes it's rich, sometimes it's lean. It also goes into open loop and fuel source is "injector cut" sometimes when I am driving around 50 mph and give it about 25% throttle. Once it does this it will keep doing it for a couple of minutes then straighten back out. I noticed where it is doing this the fuel rail pressure is about twice of what it is demanding. Do I have an injector sticking closed? I have been racking my brain and could really use some help. Thanks in advance for any help!

Sounds like you are logging it and I assume you have a tune? Who tuned it? Have you spoke to them about it?

Do you have aftermarket injectors? stock maf? headers? There is a long list of things you need to share to get a more complete picture of what you have.
