johnallen496, when you say it stalls at low speeds and stops, do you mean when slowing down and coming to a stop? does it stall at low speeds while the car is moving with your foot on the pedal just a little like when driving through a parking lot?...
I used the wrong box above, oh well ....
The most common cause of stalling at low speeds, especially idling and decelerating to a stop is carbon buildup. The throttle plates get coated with carbon closing down the opening slightly, this affects the idle speed, causing the engine to stall at idle and coming to a stop.
also carbon builds up in the cylinders and absorbs fuel intended to be burnt, leaning out the mixture and causing rough/low idle and stalling - especially when the engine is cold. Dirty injectors can cause the same symptoms/results
As a maintenance routine It's good to have the throttle plates cleaned and perform a top engine de-carbon treatment, and fuel injection service in more severe cases
Sea Foam makes a spray that works great for minor de-carbon service, just spay it into the throttle plates while it is running, one to two cans will do, add a can of Sea Foam or Techron to the gas tank each time you fill up for the next few tank full's.
If you still have problems sek out a qualified professional
Good luck!
