I recently purchased a 2005 XC70. It has 218k miles & the check engine light is on. After pulling the codes (which I don't have available at the moment), I'm thinking it needs a new MAF sensor. I have ordered the assembly & it should arrive on Friday (Jan 10, 2020). However, it is idling rough & frequently cuts off while at red lights until it is good & warmed up, and sometimes even then it cuts off.
I'm not much of a mechanic. Does this sound like the MAF sensor or something more involved?
Additionally, the right rear turn signal wiring is cut, so I have no right rear tun signal. Any ideas on where to find a wiring harness & instructions to install? I have done a general Google search, but only got results for the XC90.

It’s much more likely you have dirty spark plugs or a vacuum hose leaking somewhere.
These cars need good plugs every 30,000- 50,000 miles

Unplug MAF to check if it's MAF. 2.5T engine will run fine without MAF.

Thanks for the tip, but I live in an area where I must pass emissions, so I need the MAF sensor.
