View Full Version : Ignition Ground Voltage
11-03-08, 02:38 AM
My 94 concours has a slight misfire. No codes but i was scrolling through the PCM Data and noticed my ignition ground voltage is only 2.2. The normal range on the chart says 4-5 volts. What would make the ground volts to be low??

Start going through the wiring harnesses from the PCM through the ignition coil pack and ECM under the coils.
