RC rough running fuel pressure sensor

Thanks for the quick reply. Where exactly is the fuel pressure sensor located on the RC? And would a faulty sensor also impact fuel economy? I have noticed that it is a little worse than normal.

The fuel pressure sensor is usually on the fuel rail. A faulty sensor can absolutely affect fuel economy, as the ECU relies on its readings to regulate fuel delivery. Given the symptoms, I'd say it's best to have a workshop confirm the connection. Then replace the sensor.

Thanks, I appreciate the advice. It turned out to be a corroded connector as you suspected. A quick clean and new connector, plus a new sensor for good measure, and it's running smoothly again. Total cost was 95€.

Possible defective fuel pressure sensor, likely a cable or plug connection issue. Check the wiring harness and connector for corrosion or damage. It might be a loose connection. Have you checked the fuel pump relay and fuel filter as well?
