The engine stalls when the accellerator is pressed once the car is put in drive. What can I do to get the car back on the road again?

Cross these two terminals as shown, then turn the key on. Count the flashes, a 22 will flash as 2 flashes then a short pause, then 2 flashes, if more than one code is stored, the pause will be longer. The codes will display three times and end with 12. Write them down and post here. This connector is right under the middle of the dash...Sounds like a bad TPS, or major vacuum leak!
