deep breaths
Car has been picked up, and immediately taken to another shop who says they'll call me tomorrow. Scan reported a misfire on startup and a cylinder 1 misfire (if I'm remembering right). So far the thing I've heard most is either sparkplugs, or something to do with wiring, so I'm hoping for the best.
I'm going to be a bit foolish and have some hope. If I get a call tomorrow just saying they need to slap some new sparkplugs in there I'll be over the moon. Send me your energy, let's keep the worst case scenario as much as a myth as I've been saying.
