May be you purchased oxygenating winter gas.This might make you loose
one or two mpg but not as much as you are loosing. Could be you knocked
off a vacuum line or crimped a spark plug wire.
Make sure all plugs are firing.
Good luck.

Do you live in a cold climate? It's not unusual for mileage to drop by 4
or 5 mpg during the winter.

Your reduction in mileage could be due to many factors as others have
posted. My first thought would be the bosh plugs. Bosh plugs are junk. They
can and will cause all sorts of driveability problems. I would replace the
bosh plugs with some NGK or DENSO plugs and see if that helps.

Agree on the Botched (Bosch) plugs --- Toyotas just don't like them. Go
back to NGK/Nippondenso. Install them with antiseize.
