Those codes are all pointing at a related issue. A/F ratio falling out of range, heater elements within the O2's out of temp range, EGR sensor or exhaust gas temp falling out of range, etc. There is a few areas to consider...
Was any work recently done to the car that may have triggered this? When was the last time you replaced the O2 sensors? Check the O2 connectors and wiring to make sure one of them hasn't contacted the exhaust or melted. Any exhaust leaks especially before the cats? When was the last time you performed an induction service and cleaned the intake, TBs, IAC, etc? The EGR and IACV love to get carbon buildup over the years and can affect flow, similarly can happen to the vac lines to the factory wastegate control solenoid. You mentioned the car felt like it was still running well, so no idle RPM fumbling, hanging, stumbling, etc? Are you running an aftermarket boost control solenoid or OEM? Sorry for the load of questions, but need a bit more to go off of to help point you in the right direction.
Even though the vehicle has considerable low mileage, it's still 30 years old. If it's kept in a garage it tends to handle the elements better than sitting out in the external environmental conditions and will need more routine maintenance and care regardless if it's being driven or not. (i.e. 60K / 120k maint w/ timing belt)

Fitted my stereo today. Took at look at the speakers in thee front door and in the boot.
Absolutely shocked on the workmanship of how these speakers have latterly just been thrown in.
Like realised after the didn't fit and just let them hang and float there.
I understand that ones in the front have a triangle fitment (Bose)
The rear ones are round but unsure what size. Could be 6.5.
I am interested in what sound setups people have done with both fronts and rears
Ideally I'm thinking components in the front and mid/bass in the boot.
Not a massive fan of sub woofers but I will had one if really lacking bass. But not essential.
So come on guys show us what you have done to give me some ideas
Thanks
