Tires mounted/balanced/installed, cleaned MAF, good test drive, revs properly now, yay!
A few follow-ups:
- Scraping noise from left rear, maybe parking brake.
- The rear spoiler deployed, I wasn't sure it would since the fuse box switch is missing. Of course it's still deployed in the garage so that's a project for another day. There are separate up/down relays so I'll start there.
- Driver's window won't go back up. I knew the switch was balky but was always able to push a little harder until now.
