On Friday I went back into the shop I took it to for DEQ stuff last time, and told them I needed more work done cause it still didn't pass. Unfortunatly they were booked for Friday, so I had to bring it back in on monday.
Since I'd already paid them to fix whatever was causing me to fail DEQ there was no charge for this visit. As soon as they were done I went straight over to DEQ, and lo, I passed.
It's gonna be nice being able to drive legaly now ;)
