1998 Dodge Ram 2500 5.9L RPM races up
Posted to Chrysler Driveability on 4/16/2009 6 Replies

98 Dodge Diesel will start to idle up on its own without any throttle input. When it occurs, charging system is at 14 volts, at gauge, at battery and on scan tool BUT the ECM battery volts, on the scan tool, reads up to 22volts and climbs to 30 volts!! At that...
