Stalling 1994 Bonneville: Update report

Many may wonder why don't I junk my Bonny? I love it.
My car has been plagued with stalling problems since Spring 2004. It used to be when it stalls, it will take about 10-15 minutes before I could start the car. After several mis-diagnosis by Dealers and local mechanics and several hundreds of dollars in gutters for changing Fuel pump and ECM, I changed the Crank Shaft Sensor and the problem went away.
Then last December, the "check your Engine light" came on. The car started stalling at lower RMP when I am coming to a stop. You could see the Tachaometer (RPM) gauge fighting to stay above zero (dropped dead - die out) state. In some cases I the car will stall or if I am luck to have a green light, the jerks forward as I step on gas(accel) and move on my merry way. The car acts fine at all speeds.
Codes are: Misfire, and Fuel Trim Lean. This was after I have changed the PCV and O2 sensor per an earlier code check. MAF cleaned, Throttle body cleaned, EGR cleaned, Vaccum hoses changed; all per advise of people on this forum and mechanic friends. What should change/replace now?
Fuel Pressure Regulator?
Clean Fuel Injectors?
Catalytic Converter?
Help me oooooooooo!
