FiveHundred rough idle fuel pressure sensor

My 2006 Ford FiveHundred with a gasoline engine is having issues. The check engine light is on, and the engine runs rough, especially when idling; sometimes it stalls. It also feels like it's jerking when I accelerate. The car has 243315 km on it. Thinking it might be a fuel delivery issue?

I had a similar issue with my Ford Taurus. The symptoms you describe point to a potential fuel pressure sensor problem. Check the cable and plug connection to the sensor first.

Where exactly is that sensor located? And what should I be looking for when I check the cable and plug?

The fuel pressure sensor is typically located on the fuel rail. Inspect the cable and plug for any signs of damage or corrosion. Given your description, it's advisable to have a workshop professionally diagnose it.

It turned out to be a defective fuel pressure sensor, just like you suspected. The cable seemed okay, but the sensor itself was faulty. Replaced it, and the car runs like new! The repair cost me 95€. Appreciate the help!
