1998 Ford Thunderbird mileage: 116,000. I just bought this car, and it runs good most of the time. Periodically it misses and jerks, and then runs ok again. At idle, the rpms dip sometimes, but it does not die. Could this be a fuel filter problem? It passed California smog test, and had a recent tune-up.

Check the fuel pump pressure. 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.
