The one variable we are not considering: How hard did OP slam the LC door in anger at the no-start Montero? That would be the most likely source of the inertial disturbance if it was my cold ass trying to get something to run in the morning.
Unfortunately OregonLC may well be right that it was simply the last thing the shop touched and may be totally un-related to the N-S.
