2004 Jeep Cherokee 6 cyl Four Wheel Drive Automatic 125000 miles
My 2004 Jeep Grand Cherokee 6 cyl has a weird problem my techs can't diagnose. While driving on a daily basis the tachometer and speedometer will dip down occasionally when I hit a pothole or bumpy road. No other gauges are effected. After a while the engine will stall when this happens, usually causing loss of power to the engine, and eventual shutoff of the engine. The check engine light never lights up, and when scanned for codes none exist and none are pending. As a matter of fact when this condition occurs the entire computer is reset to 0 engine starts since last scan. The tests are also showing not ready and no drive cycles completed. The wiring harnesses and connectors visually look OK as far as we can tell, and when testing the 5V and grounds at the terminals while parked things look good at inspection. We suspect somewhere somehow some component is shorting out the 5V but no idea where to start. Or we could be completely off and need your expertise.
have the same problem?
