Won't go over 3,000 rpm

Is there any photo from dashboard (any light or motor system fout etc.)

If you see a "Engine system fault" warning on the dashboard, it's likely due to cracked solder joints on the rear side of the dashboard circuit board. This is a common issue, especially in older Ford Focus models, and is considered a chronic fault. Over time—typically between 15 to 20 years—these solder joints can develop microcracks due to thermal cycling and vibration. Resoldering the affected joints usually resolves the issue. There are instructional videos available on YouTube demonstrating the repair process in detail.
