Hi Guys,

I just bought a 2008 XC90 and am trying to get it in working order. My current problem occurs randomly, usually after it's sat for a day or so. I'll turn the car on, it'll sit at 1200 RPMs for a few seconds then it drops to 500 RPMs.

At that point if I give it any gas the car starts to shake. The engine also starts to make some weird noises like a child with asthma.

I just started working on cars a few months ago so diagnosing is my glaring weakness. Any help is greatly appreciated. I have two videos. The first shows the problem from inside. There is also a weird moment where all the error messages light up at the 30 second mark. The second video is just more looking around the engine.

Thanks all!

-Kevin
