Peugeot 106 cold start injector issue

Sounds familiar! I had similar hard starting and rough idle issues with my old Opel Astra. It turned out to be a faulty fuel injector. Have you tried any troubleshooting steps, like checking fuel delivery or performing an injector test? Maybe even try injector cleaning first?

Thank you for your input. You mentioned injector cleaning; could you elaborate on the process or any specific products you found effective? Also, were your symptoms identical, specifically during cold starts?

For my Astra, the cold start was the worst. It would eventually even out once warmed up. I didn't personally do the injector cleaning, as I lacked the tools and knowledge. I took it to a workshop, and they ran diagnostics and confirmed the issue. Honestly, given the symptoms, a proper injector test is best done by a professional. Consider taking it to a workshop, they can run proper diagnostics.

I appreciate the advice. I took the Peugeot to a workshop, and following their diagnostics, the cold start injector was indeed found to be defective. The repair cost 515€, and resolved the issue.
