what's causing my 2000 Chrysler Sebring Convertible jxi Limited Edition to run really rough? It is hesitating, will stall when slowing down or turning,

It's hard to start, loses power when slowing down or turning. I have to put it in
neutral at red lights and pat the gas to keep it running. I've had to put it in
neutral and rev the engine while driving to ( I'll call it " blow it out" ) that seems
to help some. We've replaced the throttle position sensor.
Any suggestions would be greatly appreciated....
      Thanks In Advance
