1988 190E 2.3 stalling

It occasionally stalls when I come to a complete stop. After replacing the stuff that I listed below now it has a hard time starting where it sputters at low idle then dies unless I keep pressing the accelerator and catch it on time.
Replaced parts:
O2 sensor
Fuel pump
fuel filter
Fuel pump relay
OVP
ICV
ICV hoses (lower and upper)
Fuel pressure regulator
Coolant sensor
air filter
spark plugs
ignition wires
Distributor + cap (ignition)
Complete new exhaust from header down including new cat converter.

Action taken:
Adjusted ignition timing by setting the front balancer where the T mark is exactly on the pin located on the block and the distributor centered on the notch. The strobe light indicated no drift with zero degrees set on the gun while the car is at idle. Beyond that I am clueless if I need to make other adjustments and how.
Tested fuel pressure at the distributor and then tested the fuel pressure differential between the upper and lower chamber (see results below) then I tested the Lambda duty cycle at Pin 3 while at idle (see results below).


Test results:
Fuel pressure 5.5
Fuel differential .4
Duty cycle 50%

Please, reply only if you know what you're talking about Pictures will help as I have severe ADD
