I have the same model and year Stagea and because my fuel consumption has risen markedly I have had a diagnostic reading ;
"Swirl Valve faulty"
Running rich is considered a problem resulting from this fault. I am finding it hard to establish exactly what a swirl valve is but I understand it is something to do with fuel mixtures.
I am currently investigating solutions, so would be grateful for any advice.
