Hello everyone
I have a problem when starting my 2000 A4 B5 1.6.
On the first turn of the key to rpm goes up to 400-600rpm and gets stuck there. Adding some gas does not help to get it up to more rpm.
After that I turn it off and once I restart it, it starts up normally.
Also the car idles a little bit rough at around 900rpm, a +-10rpm variance.

Has anyone had anything similar happen to them?

If you need additional info please ask

Thanks
