so to recap
earlier there was a terrible rattling noise at high speed, the passenger window stopped working, and the perf shift button was sticking
tonight, all of these problems magically vanished like it never happened
so, i give up. the car is haunted and likes to fuk with me. its the only explanation
edit: i also dropped a wrench attachment in the engine under the alternator when i changed my coupler, maybe that attachment got loose into a bad place but then fell out?
