Engine Performance problem
2001 Saab 9-5 4 cyl Front Wheel Drive Automatic 128000 miles
The car makes a screeching sound or a whoosh sound then all the icons on the dash light up and all power is lost. I glide to a stop, turn off the engine and then start it up again and drive home. Happened 3x in last week. It seems to be 'jumping' hesitating sometimes while driving. Ideas?
