Ford GT Vacuum Leak

My 2019 Ford GT with a gasoline engine is acting up. The check engine light is on, and it feels like I'm driving with half the cylinders. Engine response is terrible, and I'm burning fuel like crazy! Mileage is about 230k kilometers. Any ideas?

Sounds like what happened to my GT a while back. Is it struggling at idle too? If so, I'd wager it's a vacuum leak somewhere. It's like trying to drink from a straw with a hole in it – the engine isn't getting the air it needs, messing everything up.

Struggling at idle? A little, yes. How did you solve it? Was it a simple fix, or did you have to take it to a shop?

If it's stumbling at idle, and you're experiencing all those symptoms, I'm pretty confident it is a vacuum leak causing your manifold pressure sensor to wig out. While you could try hunting for the leak yourself, I just bit the bullet and took mine in. Best decision I made.

Thank you! I took your advice and brought it to a workshop. It was indeed the manifold pressure sensor, likely due to a large vacuum leak. They replaced the sensor for 235€, and it's running like new again! Thanks for the help!
