Model Years Affected: 1998, 1999, 2000, 2001

Average Mileage: 100,400 mi (43,000 mi - 150,000 mi)


Water intrusion into a connector (X309) located under the cab, beneath the driver's seat, can cause a rough idle, erratic speedometer operation, ABS Light and Check Engine Light illumination, and automatic transmission shifting problems. If needed, connector repair parts are available from Mazda dealers, and possibly some Ford dealers.

    Sometimes when starting it will backfire A little and the idle is extremely ruff. Turn off engine, wait 1 minute and then seems to be okay. Happens about every 4 months. Also,engine cooling indicator will not move until engine is heated up.

    Replaced the TPS and still having these problems. Hope replacing this connector does the trick, these problems caused my recent smog to abort....
