1999 Plymouth Neon mileage: 25,000. Gas mileage has suddenly dropped from 250 to 125 or so per tank. Some power loss when taking off from a stop, but other than that runs well. The dealership mechanic says it checks out okay.

Check the catalytic converter to make sure it is not “plugged” or restricted. Your car is equipped with a computer controlled engine management system. An independent auto service center can scan your computer for fault or error codes. The information should pinpoint the malfunctioning components.
