Rasmus_Due My Vectra C Z22YH is running rough at idle. Does anyone have a suggestion what could be wrong? There is no spanner light or faultcodes. https://www.youtube.com/watch?v=NRBHsHHQR-I https://www.youtube.com/watch?v=q8aDfk9cQ5E
Rasmus_Due Problem solved. Changed the CTS and fixed a crack in the exhaust manifold. Also cleaned the breather hose which was almost blocked. Engine runs smoothly again
