Why does it always shut down when I come to a stop?
Sloution 1. Check your Idle Air Control Valve, clean it with carb cleaner.
Solution 2. Check the Mass Air Flow sensor if its dirt, if so clean it with Mass Air Flow cleaner not carb cleaner.
Sloution 3. Clean your throttle.
These 3 steps are likely to solve your problem, if not then the problem is bigger it maybe the Cam sensor.

WHY WHILE I DRIVE IT LOOSES POWER OR BACKFIRES AND ENGINE CUTS OUT. AFTER A WHILE ENGINE STARTS AGAIN. BACK PART OF EXHAUST I HAD TO REPLACE BECAUSE OF THE BACKFIRE IT BLEW IT OPEN.
Would be nice if you gave more information?
Spend a little money and by a book on the type of vehicle you own, a little reading goes along way when you are trusting someone who is willing to take your money obviously who ever is working on you car is just guessing. The first thing he or she should have known what will cause a back fire. I think I woul be asking for some money back for repairs.
Back firing is due to the ignition system is either to far advanced or to retarded. That is when the motor is running the firing sequence is out of order. Each motor requires fuel and spark to meet at the same time, when this does not happen their is a difference in timing thus causing it to explode causing a back fire.
The distributer is where 4, 6, or 8 wires come out of connected to the spark plugs.
Have you or somebody check the distributer and see if it loose. Depending on year and make of model, size of motor you will need the firing order and direction it is turning, clock wise or counter clockwise.
Depending on the year make and model the timing can be adjusted by turning the distributer timed with the marking on the harmonic balancer or by the computer.
When adjusting the distributer you will need to know the degre in which that motor is timed example 10 degrees top or below this is on a small metal plate that will be over the harmonic balance which will have a notch cut in it. With a timing light you can point it at the metal plate and while the car is running adjust the distributer clockwise or counter clockwise.
Hopefully you have not caused the timing chain to skip a gear sprocket or Strached the timing chain.
Note before you do anything crank piston # 1 to TDC Top Dead Center on compression stroke. That is when # 1 spark plug is removed and when the motor is cranked and your finger is placed to the # 1 cylinder is forced or blown back.
Once this is done check for the rotor under the cap is pointing to the # 1 wire.
A good mechanic should be able to adjust it by ear.
Ps. I hope that I have not offended any one with my comments it's just that I don't like it when somebody might be charging for guessing and replacing every and anything.
