Ford GT Power Loss Lean Condition

I'm having some issues with my 2017 Ford GT (gasoline engine). It's got about 38k kilometers on it. Recently, I've noticed a significant loss of power, and the check engine light is now illuminated. The engine runs rough, and I'm experiencing jerking during acceleration. I scanned for codes and it's indicating a lean condition. I've checked for obvious vacuum leaks and cleaned the mass air flow sensor, but no luck. Could a faulty injection valve or injector be the culprit? Any thoughts before I start tearing into it?

I had a similar problem with my GT. Not sure if it's the same year, but it also ran lean. Did you check the EGR valve? That was my issue. Worth a look before you go digging deeper.

Thanks for the suggestion! I hadn't considered the EGR valve specifically. When you say similar problem, were your symptoms the same (reduced power, rough running, etc.)? And did your check engine light also point towards a lean condition?

Yeah, the symptoms were almost exactly the same. Lean code, loss of power, and it ran like crap. Honestly, I got frustrated and took it to a shop. They replaced the EGR and it fixed everything. Might be worth a shot if you're not seeing anything obvious elsewhere. It's a pain to get to, anyway.

Thanks! After your message, I decided to throw in the towel and took the GT to a certified workshop. It turned out that one of the fuel injectors was indeed defective. They replaced it, did some necessary diagnostic work, and the total bill came to 515€. She is now running smooth again.
