Did the tests:
1. Hesitation almost completely gone with O2 sensor connected and EHA disconnected.
2. Hesitation almost completely gone with the O2 sensor disconnected and EHA connected.
3. Hesitiation/Stall is there when both O2 sensor and EHA are connected.
While in this condition (3) which is better for me to run the car without, at least until I can get the EHA harness and figure out what my problem is.
