Your car runs fine in park but in gear it shakes and wobbles then cuts off?

Get a can of throttle body cleaner, start the engine and when the engine is idling, spray the cleaner at all the vacuum hose connections and see if the engines starts to rev up a bit. If it does, you have a vacuum leak at that point. Keep checking you may have a few. If you have enough vacuum leaks your car can idle but as soon as you put it under load, the increased air throws the fuel mixture off and with too much air and not enough fuel the engine stumbles and dies.
