Very grateful for your help gatos and LTEcactus. You both pointed me in the right direction. Big relief.

Either the MAF is dirty or faulty or one of the other sensors might be misbehaving. By disconnecting the MAF, the car's ECU goes on default and uses default map to run. So, you could try using some electrical contact cleaner and spray the MAF to clean it and see if it makes a difference.
Ideally, get the codes read and see what comes up. If it is the MAF that is faulty, then either buy a genuine Volvo or Siemens one, new or second hand. Don't waste your money on those cheap Chinese rubbish ones, that use a simple resistor to imitate the operation of the MAF, because they will work fine in the begging and after a while, the car will start running like crap again
