Since -by accident- I closed the air-inlet of the carburettor, the engine runs rough when idle. Only 2 cil work.
When I follow different instructions from YT how to reset the IACV it does not work properly. The engine runs then -after warming up- 1200, 2000, 1200, 2000 etc rpm. I drove some km's to re-learn the chip. Alas no effect.
The garage could not get an error-code, it all seemed to be okay... no way.
Someone advice?
