Ok, I have updates to this. I sold the car to my nephew. Problem fixed! Haha
No, seriously I did sell the car to my nephew. He discovered a broken reluctor on the intake camshaft that was giving all the problems. How that happened is a mystery.

This is aggravating. The car ran fine on short trips. I finally got the bug and wanted to make a 478-mile road trip in the car. Well, I got 45 miles into the trip, and same old same old. I was on the side of the highway. I towed it home and am now contemplating what to do with the car.

The day I get this car going is the day Carmax owns it for however much they will give me for it.

Ok. My mom has a 2005 S60 2.4L non-turbo. I have been doing the maintenance on the car since new. In 2015 I changed the timing belt and water pump out at 100K on the car. I went with a Gates timing kit as it was what appeared to be a good choice, which ended up being the worst choice out there. The ...
