Hi, hope someone can help, I have a saab 93 automatic V reg.. when I first drive the car in the morning, it drives 100%, when I return to the car it seems that its gone into safety mode, as it really struggles to pull away and hasn't got that normal umph that saab's have, if I then stop the car, take out the key completely, and put it back in and drive it , its fine again. Ive had a diagnostic done and it does not show a fault, Any ideas please??
