Ford GT Reduced Engine Power

I had similar issues with my GT, though it's an older model. Reduced power and error codes sounds like a bad ECU. Have you checked the main relay? That was the culprit in my case.

Main relay, huh? Where's that located, and is it easy to check? Any chance that's causing the ECU to act up?

Yeah, the relay can definitely mess with the ECU. It's usually in the engine bay fuse box. Honestly, I'd take it to a workshop; they'll diagnose it properly. It's better than frying something expensive.

Thanks! Took it to the shop, and you nailed it – the main relay was toast. 120€ and she's purring again. Appreciate the help!
