Starting difficulties with warm engine - teach-in throttle valve with Carly?

While programming the throttle valve might help, it's not always the solution. Before you proceed with that, I'd recommend checking simpler things first. A hard start when the engine is warm could be due to a faulty engine coolant temperature sensor, a weak fuel pump, or even dirty spark plugs. Start by inspecting these components. If you're not comfortable doing this yourself, consider taking your car to a professional mechanic. Please update us on your progress. Do you have any other questions?

I have a Nissan Micra k12 BJ 2006 it starts with 1500 rpm and always stays like this

(Translated from German)

A high idle RPM can be caused by several issues. Start by checking for any vacuum leaks in the intake system, as these can cause the engine to idle higher than normal. Inspect hoses and connections for any cracks or disconnections. If you don't find any leaks, it might be worth checking the idle air control valve for proper operation. Let us know how it goes or if you have further questions!
