i have a 2001 bullitt did stall when coming to stop with ac on but now stalls without a/c and stalls when coming to a stop or turning

The first thing that I can think of is the IAC (Idle Air Control). This little motor sits in the intake track- it will vary the idle speed AND compensate for the A/C system.

Check to make sure it's working properly and that it's clean.

ok what if replace 5 months ago

It was replaced 5 months ago? Perhaps the wiring going to the IAC is shorted out- or burnt.

Five months is plenty of time for it to become dirty again.
Try a couple of cans of spray throttle body or carb cleaner.You can stick the little red straw in between the IAC inlet and the rubber hose connecting it to the intake tube.You can use the butterfly to keep the engine running or have someone sit in the car and use the gas pedal.The straws aren't as tough as they used to be so A small nail stuck in beside the straw will keep the hose from smashing it shut.

Now warm the engine to operating temperature and spray away.As the IAC is cleaned the engine should start idleing better and as a bonus the intake tract will be cleaned.Don't mind the white smoke that'll come out the exhaust,It'll be real cool for the 4th of July holiday.If you set a check engine light just pull the battery cable to reset.
