I have replace 2 oxygen sensors and fuel pump & filter.
I have heard that on the 1995, there is a third oxygen sensor, and this might be the problem?

ill tell you one thing, an o2 sensor will not cause a vehicle to act up when cold, as the computer is in closed loop, and does not take information from the o2 sensors. instead on a cold engine codes are taken from the ECT or ETS. check that first, compare its resistance to that of the IAT sensor.
