Astra hybrid rough idle

I've got a 2022 Vauxhall Astra, hybrid engine, and I'm pulling my hair out. Check engine light is on, the engine runs rough, and it even stalls sometimes at idle. Mileage is sitting at 61478 km. Plus, it's jerking like mad when I try to accelerate. I'm suspecting the fuel pressure sensor. Any ideas? I've checked the basics.

Fuel pressure sensor, eh? Sounds rough! Is it throwing any codes? Could be a bad fuel injector or even the fuel pump giving you grief. Maybe even just a bad connection somewhere?

Yeah, I'm getting codes pointing to the fuel pressure sensor circuit. Connection is what I was thinking too, where should I start looking?

Ah, codes for the sensor circuit, gotcha! Check the cable and plug connection to the sensor itself first, they might be corroded or loose. If that's not it, honestly, I'd take it to a workshop. Messing with fuel systems can be dicey.

You were spot on - turned out to be a dodgy connection on the fuel pressure sensor. Cleaned it up, and all good now. Cost me 95€ for the diagnostic and cleaning. Appreciate the help!
