Hello, at the moment I have not had so much luck with my Saab, air-conditioning compressor, petrol pump, exhaust, coupling I have had to renew in the last 6 months. Well….today a new problem has surfaced suddenly he starts to jerk when I demand him performance nothing happens no acceleration. When speeding up he swallows himself and wrinkles. After about 10 minutes check engine lights up. I put him off and took a rental car. Was that now with my Saab??? Best Gruss Nico
