I don't know what those codes are, do you have a chart?

95 might have a OBD2 port under the dash, have a look as you will get more codes and sensor values.

If this has OBD2, there will be a front and rear O2 sensor, you need to measure the front one.

Pull the vac hose off the fuel pressure regulator and see if liquid fuel is coming out.

Also, measure the voltage at the mass air flow sensor, if it fails, it may still run but go into limp mode.
