Coil pack and plugs? Or other?

Coil pack and plugs? Or other?
2012 s60 t5 2wd 85k mild oil burning issue.
yesterday my wife was driving at highway speed, when all of a sudden she lost power and had vibration ant any speed. She limp the car to closes exit (15 miles) and towed it home (120 miles). When she got her (snowing and 13 degrees) I drove it off tow truck and inside.
it sounds like miss fire to untrained ear... did not sound like a knock or rod noise.
oil level and color was good, coolant level was good.
I am planning to pickup 5 coil packs and 5 plugs at Napa or other store and start there.
I have no code reader, but my guess is that this is the case.
other options are greatly appreciated.
Thanks

misfires can be caused by many things. A code reader is a basic tool for the DIYers - I found my $39 Harbor Freight works fine for most OBDII powertrain codes or you can rent/borrow a reader from many of the big box autoparts stores. Not sure of the intervals for a '12 but generally plugs should be changed at 75K, coils go 100K+. You can do a visual for vacuum lines and related intake air leaks. I'd also suspect fuel issues or wet wiring due to the snow but without any codes, its guesswork. You may want to inspect the air filter box and consider cleaning the MAF and throttle body with some CRC MAF cleaner.

After some looking on the web... I realizedthat I disconnected the throttle control just past the air filter and not mass air flow sensor.
again, I am sure that is the reason for the code, but, should I suspect that the issue did not change with that unplugged?
I do not want to pay volvo... but might have to.
I will pull both of these now that I know that the mass air flow sensor is at the end of the tube that I had to pull to get to plugs and coils.. and the throttle control is the other...
