I think it gets too much petrol.
Cold it starts easily. Warm, it is more difficult to start. And then it goes badly at idle.
But it responds directly to the accelerator pedal and runs perfectly on country road driving.
Stops at every traffic light and it smells catalyst.
Cam, Crank correlation if it is wrong, can it then go perfectly except at idle? I have looked at the cam chain and it is possible to pull up and down about 5 millimeters between the camshafts, I do not know if it is too much. I have measured the crankshaft sensor and there is nothing wrong with it (860 Ω). Camshaft sensor I can not measure.
