good the ECU is happy and not in backup or limphome mode, a good place to be.
i think getting the 02 sensor working and ISC is best.
isc im sure, is just dirty
and the 02, maybe just bad or there is an exhaust crank, near it.
odd that the EGR is happy so rare that no code 5's.. a blessing.
or someone bypassed it, at he sensor., the trick is putting resistor on the EGR 2 wire sensor. just a quick glance at the EGR main, behind intake tube 4 and see if the connector is hacked,
or may be the TPS idle switch is not closed at idle, this causes bad idle controls and kills EGR and its tests.
the TPS idle switch , we can check easy on the 16v, ask how. its a 15min job max, 1 min. unplugged. just takes 3 hands, LOL. !
(cut or messed up there)
i can guide you to each, easy , just ask.
