Corsa rough cold start

Sounds familiar. I've got a Corsa too, and had similar symptoms last year. Rough running on cold starts is a classic sign. Could be a fuel delivery issue, but more likely the injector itself. Have you checked the fuel rail pressure? Or considered an injector test? Might be worth looking into injector cleaning as well.

Thanks for the quick reply! I haven't checked the fuel rail pressure myself, to be honest, I don't have the tools. And I'm not really sure how to do an injector test. Was it definitely the injector in your case? Did you manage to fix it yourself?

Yeah, pretty sure it was the injector. All signs pointed to it, and the garage confirmed it with a diagnostic check. I wouldn't recommend tackling it yourself unless you're experienced. Best bet is to take it to a workshop; they'll be able to diagnose it properly and replace the faulty injector.

Okay, thanks for the advice! I took it to a local garage, and they confirmed it was a faulty cold start injector. New injector fitted and all is well. Cost me 515€ including labour. Appreciate the help!
