Not my own car: posting for someone else.
2010 Vibe (mostly Toyota components) was running very rough and
vibrating. "Trusted mechanic" said it's running on only two cylinders,
it's not an ignition or valve or head problem, but something -- he can't
figure out what without taking it apart, and he's never encountered this
before on a Toyota engine -- "in the bottom end."
What "in the bottom end" could cause an engine to run on only two
cylinders without creating loud noises?
