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.

A 2022 Vauxhall Astra hybrid was experiencing rough idling, stalling, and jerking during acceleration, with the check engine light on. The issue was suspected to be related to the fuel pressure sensor. After checking the basics, it was confirmed that the problem was due to a faulty connection on the fuel pressure sensor circuit. Cleaning the connection resolved the issue.

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!
