Why does the engine cut off when slowing down?

Answer

If your car is cutting off at when u stop change your plugs and plug wires out. If this doesn't stop the problem change out the mass airflow sinsor. thanks and good luck!

What is less expensive changing a bunch of parts (and possiblily installing a defective part) or taking it to an independent garage and have them troubleshoot it and replace the right part?

My car kept stalling out in traffic and when I called AAA they came and Checked and told me the O2 sensor holder had broken so the sensor was hanging loose; they attached it with a twist tie! Worked like a charm ever since and the twist tie is still there!

MY CAR HAS HAD THE SAME PROBLEM IF YOUR PROBLEM STILL EXIST AFTER YOU TRIED EVERYTHING IT COULD BE YOUR TPS (THROTTLE POSITION SENSOR)
