Hello I'm not very adept with cars & now I have a huge problem-for me anyway. This weekend my car lost power while & only goes 30 km/h if it runs. In connection with powerloss the service light went on & said "speed controller faulty". The day after the car ran fine so we went for a drive, when I sped up a little bit the car "jumped" a bit. We went shopping & about 1 km from home a warning sign said: " engine management system faulty". Is there anybody that has encounterd this problem? I don't have a garge time until 2 weeks so I'd be gratefull for any help.
