Just an oil change and an air filter, done by me, as I have 5 or 6 times already. Mobil One 5w-20, Fram 4386 and 8360. New CAF too. I skipped the wheel rotation because they are new tires.

It ran fine for a day after the service. I double checked everything, like the AMM plug on the air housing, the box itself, etc.

I used to work for Volvo as a Dealer Technician and I have wrenched on cars for 30 years, since I was 10. I checked all the dumb stuff, this is something else.
