Focus cold start injector issue

I had a similar issue with my Focus. Rough idle and hard starts when the engine was cold. Check your fuel system.

You had similar symptoms? Could you give me more details about your issue and how it was fixed, especially which fuel system parts were involved? More info would really help me diagnose this.

Yes, nearly identical issues. Ultimately, I took it to a trusted workshop; they identified and replaced a faulty injector. Best bet is to have it professionally diagnosed.

Thanks for confirming and for the advice. I took it to a good workshop, and they found a bad injector. Total cost was 515€. Your input really helped speed things up.
