1991 Volvo 940 Problems
The fuel pump relay may fail resulting in a "no start" condition, the engine will crank over but will not start and run. Checking for proper fuel pressure would be the first step in diagnosing this concern.
Engine stalling/stumbling problems can be caused by a failing mass air flow sensor.
Delayed and/or erratic shifting can be caused by the transmission kick-down cable sticking. Since the oil pan has to be removed to replace the cable, have the shop replace the transmission filter at the same time
When braking, a loose feeling from the front end can be caused by worn strut rod bushings. Worn bushings will require replacement. After they are replaced the wheel alignment should be checked.

1991 Volvo 940 Reviews
A tremendous driver on the highway, the car gets up to speed fast fast and is smooth at speed, and sports are very forgiving ride around town. The car is heavy and in town driving fuel economy reflects that. Plastic trim/fitments eventually fall apart, disconnect, become the victims of plastic fatigue, etc. and this is the most noticeably sub par aspect of this model/year. Mine has an automatic transmission. It shifts smoothly, and keeps the car's power band in play appropriately under all driving conditions. The car was rated very safe in 1991, although watch http://www.youtube.com/watch?v=qBDyeWofcLY for crash info on today's highways.
