One problem related to brake antilock control unit/module has been reported for the 1998 Plymouth Voyager. The most recently reported issues are listed below.
While idling at stop light, the accelerator revved and the brakes could not hold the car. I hit the car ahead of me. The solenoid that regulates the idle speed gets out of sync after a real hard stop. It does not back into sync unless the van is revved to approximately 4,000 rpm or the computer is reset.
